I'm in a similar situation. I've basically been disabled by the fallout of bipolar and psychiatric treatments. I think the only reason I've made it this far is because I developed a daily routine. However, the impression that I'm nearing my breaking point has gone from primarily psychological to physical, as if my body is beginning to reject my efforts to continue trying to find a way to make things work. Just, exhausted, frightened, scared, fearing; always fearing that trying harder doesn't work; that my efforts are futile; that my sense of hopelessness has been built on solid foundations and all my efforts to shake it free from my world will be in vain.
