Therapy can help. In fact in therapy we have discussed this very thing. You cannot go back to thd past or bettervtimes but you can become stable and create a future your proud of. I've gone from being normal to being crazy, of course i wish i were normal crazy hit in my 30's. But meds make me normal and the blessing is i qualify for disability can pursue my dreams. Working part time i make more than i did working full time. I have better insurance. All because i am disabled.
There are things i miss about my old life many things but i write songs about it, and try to prosper in my current life. I fantasize about making enough not to need disability but i haven't made it big yet. I am really learning a lot from therapy it's helping me appreciate who i am and not live in total regret, believe me i have many especially when it comes to my deceased son.
