You also went cold turkey on your meds dear. Most meds have side effects if you've been taking them for a long time and suddenly stop. Zoning out or not remembering what happened can be one. My bf (not on any meds) after his grandpa died once tore up an entire roll of paper towels for absolutely no logical reason he could find. He wasn't even aware that he did it until he saw the mess a few minutes afterwards, on top of his stuff. Strong emotions can do a lot of things to a person, even without adding meds or possible side effects/withdrawls to the mix. Call your pdoc and your T and discuss it with them.

p.s: Totally not trying to be condescending by calling you 'dear' just so ya know! ♥ I care.
