I could be 100% off the mark here but i just want some opinions from experienced people i have major depression and BPD as well as some other things but my psychologist said something which got me thinking anyway does this sound like mania?

- i will start singing randomly and cant stop or i cant stop talking
- my thoguhts race really fast
- i have heaps or random ideas
- feel like i can do more thing than usual
- have lots of epiphanies
- dont sleep but i am not physically tired
- i feel very revved up and cant sit still
- do more things than usual
- feel like i can do anything and it wouldnt matter

These things sometimes happen by themselves and i dont normally feel happy just full of a strange kind of energy and can last from a few hours to a couple of days at most i think like 2 weeks though and sometimes i feel like this and also VERY depressed and the SAME time which is very confusing for me.

Any thoughts would be very helpful.
