You are so very right that killing yourself solves nothing. I believe in karma also.
I took trazadone for awhile and I slept well while I was taking it but about a half hour after I took it I felt some chest pressure. I doubt it was cardiac in origin but nevertheless it was disconcerting so my doc stopped the trazadone.
I took lithium for awhile but my pdoc at that time only checked my blood levels once and I became toxic. Many people do well on lithium though.
I am glad you have joined psychcentral and I hope you find the site helpful.
