Yes, we can't do what normal people can. Mental illness is a tough b**ch. The only ones that can have a mild mental illness... it doesn't affect them to a high degree. If I were to try and live a life of a normal person right now, I'd just shoot myself due to the insane chaos that would be triggered.
I also have severe OCD, fortunatly it is greatly controlled when I avoid triggers (in the past OCD was worse and I could not escape it). OCD is debilitating, from what I heard, rarely does medication help it, plus its only a temporary help as medications cause tolerance, and withdrawal once you get off.
I am aware that if I make a dream, it would have to be small. My small dream is to somehow have an income of money to support myself, not to be rich because I get no joy from material things anymore. Even this dream is mostly likely impossible because of my checking OCD and pure-O OCD. It would have to be an income that requires very little contributions and effort from myself, because effort gives me obsessions and compulsions.
