I had zoloft withdrawal, it just stopped working for me. And yes I felt non functional, but what really caused me to notice and talk to my doc were the brain zaps. I would get these random jolts of what felt like electricity in my brain. So from my very narrow sample size. I would say look up withdrawal signs for your medication and if you are fitting those then definitely go back to you doc.

I also have adverse reactions to most mood stabilizers so... yay medication roulette!

Sorry, wish it was less difficult for you
