That sounds horrible, and much worse than my experience with "losing it". I had a medication-induced hypomanic episode. I stopped eating and sleeping for three days, but never felt tired. I was paranoid, severely agitated and would fly into a rage over small things. I also had what are called "ideas of reference". I thought ordinary things I encountered were placed there specifically for me.

The solution was worse. I was put on risperidone to halt the episode. It was a total 180, in a bad way. I felt stupefied and sluggish. I couldn't put two thoughts together most of the day. I ate everything, everything; once to the point of vomiting. I had extremely vivid and bizarre nightmares nightly.

It was a Catch-22 situation. I needed the antidepressants to battle winter depression, but SSRIs were the only ones that worked. However, those have a well-known side effect of triggering mania in people (and in my case, for sure).

Happy ending is that I moved to the tropics and haven't had to take any medication and have had no relapses since the move.
