Mental illness might begin with some very mild symptoms, where it's something noticeable, however, most mind might not be aware of them, or might not recognize that as the beginning stage of mental illness, as these symptoms seemed to be something 'common' and nothing 'bad' or 'wrong' to many minds that are thinking, behaving, acting and reacting in the way that is under the influence of ignorance, egoism, impurities and restlessness. And if without paying attention to be acknowledging that beginning stage of mental illness, as well as continuously empowering the mental illness out of the ignorance and egoism from oneself and others, it will eventually grow into a more serious and intense level of mental illness, and if there's still no awareness towards helping oneself to come out from such mental illness, it would come to a stage that it's too late to be doing something about it.
None should be discriminating towards other people or themselves who are being diagnosed with certain type and degrees of mental illness, not to say, there are many minds are not even aware of themselves are suffering from certain type and degrees of mental illness, but we should be compassionate towards the minds that are suffering from certain type and degrees of mental illness, however, being compassionate towards mental illness sufferer doesn't mean that people should be empowering their mental illness.
When the mind starts to think, behave, act and react in the way that hurt oneself and others, either wittingly or unwittingly, losing the clarity of thinking, reasoning power, self-awareness and self-control, affecting the relationship with some others and the surrounding environment, out of the disturbed suffering states of mind under the influence of ignorance, egoism, impurities and restlessness, being over-powered or over-whelmed by the desires of craving and aversion, sensitivity, annoyance, irritation, frustration, disturbance, disagreement, dissatisfaction, greed, disappointment, anger, hatred, jealousy, envy, resentment, pride a.k.a. low self-esteem, superiority and inferiority, fear, worry, stress, hostility, animosity, victimized, hurt, grief, sadness, unhappiness, physical/mental/emotional pain and discomfort, self-protectiveness, possessiveness, defensiveness and offensiveness, that are the symptoms of a mind that is unwell.
How people commonly deal with those who are suffering from certain type and degrees of mental illness, out of sympathy that is under the influence of ignorance and egoism, is by not mentioning anything about 'mental illness', or 'what the minds want to deny or runaway from, or don't want to confront with, that would be upsetting or offending the minds', not to say, 'seeking help to come out from mental illness' that most probably will trigger the minds react in the way of, "No! No! No! this is upsetting me. I don't want to hear or talk about it! This is hurting me. I don't like this. I don't want you to talk about this. You are hurting me! Why do you want to hurt me? Why are you attacking me? You are making up all these things. You are the one that is mentally ill. I am fine. I have no problem." Especially if the mind is being over-powered by pride and arrogance and defensiveness, it feels that it is being attacked or humiliated by such 'accusation'.
And that kind of 'sympathetic' way of trying to console the mentally ill minds and not wanting to be upsetting or offending the minds that are trying to runaway from certain unpleasant and disagreeable reality that they don't like and don't desire, that are painful or hurting to them, that they don't know how to understand and be able to let go, and that they don't want to confront with, by not mentioning 'mental illness', or 'seeking help', or 'maybe do something about it', as well as the practice of untruthfulness and hypocrisy while interacting with the minds that are suffering from mental illness for many years, doesn't help these minds to come out from such suffering.
Meanwhile in certain cases, people would tell these minds, "Hey! There's nothing wrong with you. You are not ill. You are fine. Look! You are all good and nothing wrong. You were hurt by those who are bad and wrong. You don't deserve all that. All those bad people who had hurt you deserve to be in painful suffering, not you. You deserve sympathy and empathy, love, accommodation and support as much as possible from all and everyone."
Out of 'such loving kindness' towards these minds, people will even try to justify, ignore, deny, or even cover up certain damaging behaviors of these minds that hurt themselves and others under the influence of such unattended and empowered mental illness. Especially, after random hurtful behavior, action and reaction out of the disturbed suffering states of mind, certain minds that still have some awareness towards their behaviors, actions and reactions are being hurtful, and they would be apologetic, and be 'loving' afterwards, for a while, but that also doesn't help them to come out from the suffering of mental illness, and they would be continuously behaving, acting and reacting in such hurtful, disturbing and damaging way from time to time, out of the existing, or suppressed, or empowered mental illness, that was being unattended, denied and empowered by oneself and those around them who would always justify and cover up such damaging hurtful behaviors, actions and reactions out of what they think and believe as 'love' and 'understanding'. It's not.
Many people are suffering from certain mental illness because they were being abused or hurt by those who are suffering from mental illness, and then, they also starting to be abusing or hurting others, or their relationships with everyone, either wittingly or unwittingly, under the influence of mental illness, or the disturbed suffering states of mind. Such 'console' out of 'sympathy and empathy' as well as 'untruthfulness, justification, cover up, denial and hypocrisy' under the influence of ignorance and egoism doesn't help the suffering minds to come out from the suffering of mental illness, but empowering the mental illness to the deepest.
Compassion towards the mental illness sufferer, is about allowing them to have the opportunity to see what is going on in their minds, without judgment, aversion or fear, to be aware of and acknowledging the presence of mental illness or the disturbed suffering states of mind, without attachment, identification, judgment or association, even if in the beginning, the minds would be upset or offended by the inevitable process of seeing and acknowledging the existing 'illness', or 'disturbs', or 'pain', that nobody would like to have.
Even if they might not want to confront with such unpleasant or painful process of acknowledging the reality of, "Yes, I am not well. My mind is not well. It's very upsetting and painful to deal with all these. But, it's okay. I just need to help myself to come out from such suffering. Because nobody can help me if I don't help myself," but at least, through such honesty, there's hope or opportunity for them to be opened to see what is going on in their mind, or not, and then to decide whether they want to continuing to be in such disturbed suffering states of mind, and continuously hurting oneself and others under the disturbed suffering states of mind, or, they want to help themselves to be free from all that, to stop hurting themselves and others either wittingly or unwittingly, out of such mental illness or disturbed suffering states of mind, by looking into what is going on in the mind, without fear or aversion, without judgment or identification, to know and understand what is the root cause of such disturbed suffering states of mind.
Only by knowing and understanding the root cause of the disturbed suffering states of mind, will enable the mind to be letting go what the mind thinks and believes as hurtful and painful and undeserving, effectively. Then the mind will not be determined or disturbed ever again even the past unpleasant and undesirable memories are still there, and there's no pain, fear or aversion towards mentioning or talking about those unpleasant and disagreeable experiences. That is truly coming out from the suffering of mental illness or the disturbed suffering states of mind. Not by ignoring, or denying, or pushing away, or sweeping under the carpet towards all kinds of past hurtful, painful, unpleasant, disagreeable and undesirable experiences and memories. Not by blaming oneself or others for what had happened. That doesn't need to involve the action of forgiveness towards or the presence of apology from those who are suffering from mental illness, and hence, behaving in the way that contribute to mental illness or the disturbed suffering states of mind in others. But just by understand. That is liberation.
"I was hurt. That's why I am hurting all and everyone now, either wittingly or unwittingly. I am hurting all and everyone is because I am mentally ill. I am mentally ill because I was hurt by those who are mentally ill." That is mental illness that goes on in a loop. This loop can be stopped, if there's a will to understand, and be free.
Inquire the truth of everything.
