Seeking Advice on Lithium and Mental Blocks

Hi! I developed symptoms of a mental disorder in 2005. I’ve had many ups and downs and it really derailed me from many things. I’ve come to realize that while I needed hospitalizations many times, there were times I which I could’ve experienced different outcomes. I’m trying to develop a life that works for me. What are your experiences with lithium? And getting past mental blocks? I feel as if I fear exerting myself and attempting things. I’m afraid I’ll get sick again. I don’t want to be hospitalized anymore. Also, do any of you hear voices? I do, and sometimes wonder if, as many shrinks have said, I have schizoaffective disorder instead. Anyway, I know this is long. I need advice.
