I am not any help to you, but I wanted to welcome you, and tell you how sorry I am that you are suffering like this.
The way you described yourself as being before hospitalization sure sounds more like BP1 than BP2. But I am not a doctor, and would never try to tell you "yes you have this, or that".
If you are not happy with the psych you went to, can you get a second opinion? Being hi or low all the time can affect your health long term. You need to be stabilized.
I hope you get the answers you need, and get on meds that will work.
