I was diagnosed with bipolar type 1 while in the hospital. The thing is, i’m pretty sure I’m type 2. I never had really long manic episodes. They would only last a few days. That’s not what confuses me though. Recently, I’ve had episodes of extreme highs and extreme lows within hours. Before my last hospital visit, I felt on top of the world, not in a productive way, but I was so incredibly happy. I kept giggling at everything and I felt extremely high. My chest was tight with anxiety and I started to feel derealization. I started to feel like I was in a meat suit and just controlling my body parts remotely. I didn’t feel like I was real, almost like I was in a dream. Then that feeling of giggling and not feeling real quickly turned into a severe depressive episode that landed me in the hospital. Does anybody else ever experience these short lived highs? Is it even mania at that point? Some days this happens. They upped my antipsychotics and the episodes are way less frequent, but I’m still wondering what is going on. 
Anything helps!
