It's strikes me you've had elevated mood - doing all those things, and maybe mixed states with all your different feelings. My thought is that you need to consciously and physically calm down. Set in place a range of things such as a bath with aromatherpay oils, get a massage, go for a very quiet, mindful walk.

Maybe check your meds are OK, or do they need an adjustment. We can't adjust our attitude if our brain chemicals are out of whack. And as the school stuff, maybe use the Serenity Prayer to look at the parts of things you can change about the situation, and the parts it's not in your power to change. You could get great relief from this. (I'm a sober AA member as well as having Bipolar and panic and anxiety disorders). I hope you feel better soon.
