Niki, I think that first of all, you must change of doctor, because I had the same problem, I was on
zoloft for 5 years and then I stopped cold turkey and I was off the medication for a year, in that year I had a lot of physical problems, stomach, the nerve of my ankle, etc, until the depression, anxiety and panic attacks came double. So, as far as I know you shouldn't quit the antidepressants cold turkey.
I would suggest that go with another doctor and maybe he or she will put you on medication back again, I don't know if it's going to be
Lexapro or other one. Then maybe, when you feel ok, he or she has to withdraw the medication very slowly.
