I am not a doctor either but it sounds like hypomania to me, mixed maybe? but pdoc says I'm mixed right now, I have a lot of depressive thoughts but do things like speak quickly, interrupt people talking, can't sit still. To me it sounds like you could be near mania again? Not sure of what full mania is for you. I think it is best to see your pdoc ASAP.

How much sleep is enough for you?

There may be exceptions, but going from suicidal to stable so quickly does not seem normal to me. I think I went from depressed though not suicidal slowly to stable such as this with med changes:

I had a stable period (around 6 months, I wish so badly I could get back to that), I was able to concentrate on & finish big projects without having tons of stuff going on and a bit more creative (easier to find solutions to storage problems, not like a huge creative leap), sleeping 8 or 9 hours a night, cooking from scratch instead of relying on pre-made meals. But that was about the extent of it.
