Why would you not want to taper or get help from medical personnel? That's not a good judgment decision. That just sounds like deliberately asking for more side effects/trouble than you need. Sounds like a precipitous decision not in keeping with the seriousness of the issue. Also sounds like SI.

"By stopping cold turkey, serotonergic activity will drop drastically. Hence withdrawal side-effects may appear such as electrical surges/shocks in the head (brain shivers) and/or body, pins and needles on the skin, feelings as being on the verge of losing consciousness, blackouts, short term memory problems, etc.. Above mentioned side effects refer to epileptiform activity, or electrical discharges, in the brain. When dosages are cut back, (withdrawal) side-effects are at least minimized. No one should stop taking their medication cold turkey, but anti-depressant use should be tapered off very, very slowly."
