Withdrawal (or discontinuation syndrome as they like to call it) can be a complete trip.
I thought I was losing my mind when I went off my meds and I tapered them very reasonably. Please taper more slowly and/or contact your GP/Pdoc for help.
I have never been psychotic, but someone was telling me (in my head, but not me, but not someone else....confusing right?) that it would be a good idea to burn down my house with all my family in it. The point is that in the end, I was convinced it was the right idea.
Meds can make you think and do some scary stuff. PLEASE BE CAREFUL!
