It's evident that you lack the ability to understand the complexity of mental illness. I'm not sure what truth you think 'people' don't want to accept but I can say from experience it's more complicated.
I've struggled with mental illness and I work directly with the mentally ill. Your lack of understanding, compassion and empathy is unnecessary. This is what leads to mental illness being stigmatized and leads to people refusing to seek help for their struggles.
So many people believe it's a matter of pulling yourself up by the bootstraps and it's more complicated than that.
I think you are missing the fact that there are people who have had to deal with extreme trauma and things like that. Those people don't feel sorry for themselves. They have more to process and more to come to terms with. That takes time, patience and understanding. Everyone has to help themselves and the majority of people do but you are disregarding the fact that there are complexities that lead to people taking more time to heal and move forward. It is not a one size fits all like you are making it out to be. It's a combination of helping yourself and learning to navigate things like mental illness and trauma and life. It's actually kind of sad that you cannot acknowledge that it's a complex thing.
I recall you making a post about not judging others. This entire post is full of judgment and shaming. Maybe you should go back and reread what you wrote in your previous post.
