Going on and off anti-depressants can do crazy things to us bipolars! Maybe you could talk to your doc about reducing your dose?? A lot of your symptoms do sound med related. It is a concern.Though it is good you are aware of what is going on. Feeling that way is awful. I hope you find a solution where you can not feel so dulled but do not fall into an episode.
