At this point it sounds like you need psyciatric drugs to deal. No shame in that, we all need them to get by during hard times. I would concentrate on that first, then worry about the mercury. The damage the mercury has done can be helped greatly with supplemental support (but you need to know which hormones and functions are lacking though) and allopathic meds. See a doctor, get help. There really isn't anything more anyone here can do for you on the psycosis front.
