Based on this thread and the other one you made, I'd say you've crossed into hypomania, but that's just my guess I'm no clinical expert. It seems like your lack of sleep and feeling awesome isn't usually to the extent that you feel the need to ask others if you should be worried. Get in touch with your doc, have an honest conversation with them, and see what they say. Enjoy the fun feelings while they last but try not to do things to exacerbate it (cut down on caffeine, if you can't sleep at least rest in your bed every night, listen to relaxing music as opposed to stuff that pumps you up, etc).
