Looking for some help honestly

Hey there everyone! So I just got diagnosed with bipolar 1 like a month ago affter a stay in the psych hospital (man, what a whirlwind). Right now, it's all over the place-feeling super happy one minute and then flipping to angry the next. It's kinda rough, honestly. I end up arguing with my boyfriend and feel like everything is crashing down around me. My head feels so loud too-it's crazy sometimes.

The rage thing is really hitting me hard right now, and it's tough because I can't seem to figure out what sets it off afterwards since my memory is all fuzzy. If anone has dealt with something similar and found ways to cope, any tips would be seriously appreciated!
