I Have Been On Prozac For Over A Year And

I have been on prozac for over a year and a half. I was on cymbalta and that was pretty bad withdrawal after five years.
I would like to be drug free. Now I have switched over to cylexes. I went right from prozac to cylexes. I am nauses in the a,m, can not really eat. Suggestions. I need to eat etc. School is starting soon and I need the energy. I cry for no stupid reason. My boyfriend broke up with me cause I showed (to much emotion) I believe. Anyway is cyclexes any better than prozac, I really did feel anything with the prozac.
