There is a state in bipolar I disorder called a mixed state which is exactly what you described. I had the same thing a few times last year. Super energetic but super irritable, angry, and dysphoric. Those are the times I feared for my safety because in a depression I still have impulse control, so even if I want to die I won't take steps to make it happen because I can think it through. In a mixed state I have intrusive visions of my chosen method and I can't resist. I was hospitalized all three times for my own protection.

As for the doctor, you can try to go to your GP if you are concerned. Mine wouldn't help me because it was too complex but I live in the US in a state where there isn't more than a two month wait for a pdoc. The only thing I would say about that is if you think you have BP 1 stay away from antidepressants until you can see a pdoc. They can cause manias or mixed states (mine were all med induced). You don't want that unless you have someone to call on.

Honestly hough if you've made it this long without meds it won't hurt to wait until May unless you are concerned now. If you are, definitely try to see your GP.
