Hi Jimrat,
I've never taken Zoloft that I recall, but I've had similar lasting side-effects from other psych drugs. I've been off the drugs now for three years (was on them for five - a range of things, anti-psychotics and anti-depressants especially), and the physical symptoms have never left. I get a very severe anxiety sometimes that exactly correlates with heart palpitations I first experienced on an antipsychotic, that drug was stopped due to the heart issues but neither the anxiety nor the tremors ever left.
To quote you, "I know my body and I know what happened". Nobody has ever acknowledged these things; I doubt they ever will. It hurts. I don't have any advice how to deal with it, except to say that you're not on your own. hugs, eh?
