Shame comes in many forms and sizes, depending on what circumstance and scenario you have experienced. A majority of people suffering a mental illness will always, always feel an intense feeling of shame after people have witnessed them at their worst. The more people run from it, the shame will be heightened. The person suffering wont fully understand how when they are sick and show the symptoms of their sickness, they some people just cannot be bothered dealing with them.
Why should someone with a mental illness feel shame, which by definition is to feel a painful feeling of humiliation or distress caused by the consciousness of wrong or foolish behaviour? This is where I want to extend my strong point, there is no shame in having a mental illness. There is no shame, absolutely no shame, in being ill and reacting from your symptoms of your mental illness. There is no shame in Suicide ideation, and there is absolutely no shame in the way you behave when you have a irrational mind, especially if you have a debilitating illness that impacts your every day life.
To make someone feel ashamed for having a mental illness is also morally unjustifiable. Everyone experiences things differently, so why do you get to decide that the way they are behaving when they are ill is 'wrong'? I will always bring it back to this example, people become severely ill in other illnesses and lash out when they are in pain, why is it any different? Sure, you may think some illnesses can be controlled and mental illness isn't an excuse to behave certain ways, but do you know people's triggers? Do you know what sparks up their reactions? Maybe you should ask them, so you can form a better understanding and if you really care enough for this person, you would do anything you could to make sure they stay in your life, no matter how challenging the illness may seem. I am not asking people to dedicate their whole entire life to supporting someone who is ill, there are just small things people can do. They always say they 'cant' support someone who's mentally ill, when you can. There is no such thing as can't, and there are so many skills out there to help them not feel ashamed for being ill and impaired.
At the end of the day, mental illness does need professional help. We are a minority in the system, and we have to suffer the repercussions of a flawed system as well. We don't have the help readily available, and especially if you are just putting your foot in the door with the mental health system. What we need is general understanding from society, and to be acknowledged. You should never shame someone for being mentally ill and you should never, ever shame someone for acting irrational when they are feeling paralysing pain.
