If you are dysphoric (bitchy,) then you might need to be careful about adding an antidepressant. You may want to try adding another
mood stabilizer, but probably not lamictal, because it is typically activating, and it sounds like you need more of a downer. If I were you, I might talk to my doctor about switching to Trileptal--it's like Tegretol with less side effects.
I took Trileptal and Abilify for a while and it made me a nervous wreck, which I now think was from the Abilify.
