Its interesting you get on with Zoloft, I was not compatible with it at all, but then again I suppose we are all different !
I know how not trusting your senses can feel like, and I can't provide you with any brilliant magical way to sort it out (I wish I could !) When I was younger I never actually realised i was hallucinating untill someone would be looking at me in a rather puzzled way

Hope your doing well.
