I was never able to deliberately bring on a hypomanic episode myself, back when I was dumb enough to try. I barely need sleep when it's happening and I believe lack of sleep makes it worse, but barely sleeping doesn't seem to cause it for me.

I would caution against trying to trigger it though, especially if you're already starting to feel depressed. What lack of sleep does is introduce instability, and the outcome is out of your hands. You could induce a mixed state. I've been dealing with the dyshporic version of hypomania this summer myself, and it's like being stuck in a nightmare. Hypomania isn't always the positive energy. Or you could just make your depression worse. Or you could bring on anxiety.

I would recommend listening to Miguel'smom and focus on resting and being healthy right now.
