I Feel Useless and Helpless

I'm not sure if I should feel happy or sad at the moment, I feel so lost within myself on who I am and what I've done I've moved out of home about 2 months ago and I don't know how to feel, I've gone through so much stuff and I'm not depressed or sad about it and what I'm going through now is worse than what I've ever had to deal with in my life, I guess what I'm really trying to say is how am I suppose to feel now that my life has changed... I had extreme psychosis and severe depression and anxiety... Now I'm off my mess and have been on them for a year, I haven't self harmed in over 1 year and 6 months, and I've been off drugs for over 8 months I just don't understand how I am handling things as well as I am.
