Mania on STOPPING antidepressants

Doc had to cut my meds recently due to unwanted side effects. A few days later I'm not doing great.

I've not been diagnosed with bipolar (my formal Dx is DID), and I've never thought it a possibility until the last few days. I'm climbing trees, yelling at strangers and play fighting invisible people..

Have you ever heard or experienced mania on serotonin
Withdrawal? I feel like I'm grasping at (reality) straws. If it's mania, is it possible that I'm more 'at risk' then I think I am?
