Hey. I think depression can definitely make me feel flat sometimes, It can also make me cry for seemingly no reason at times. But over medication can also make one feel flat sometimes- when I first started lamictal the first time it made me feel too stabilized- like I didn't have a normal human range of emotion or something. Luckily that side effect didn't last too long.

You say you got off everything but the lithium because you wanted to feel. And now songs are making you cry. Maybe that because now you ARE feeling, and your brain has to get used to it after being overmedicated and flat? Its a possibility anyway. And it is somewhat tramautic on the brain to suddenly stop strong psych meds- it may take some time to feel more like yourself.

In my experience, pdocs are much better putting ppl on meds than they are at taking them off. Mine have not always been so knowledgeable on how to slowly taper off of medication to avoid discontinuation syndrome (withdrawal effects).

Anyway I hope you start feeling better soon. Take care.
