Welcome to PC!
It is world changing accepting a diagnosis like Bipolar. It certainly was for me. But it also made a lot of sense when I looked back at my life. So all at once I was deeply shocked and relieved. Well that’s my experience.

Your symptoms certainly seem Bipolar. You said you’ve been diagnosed. Are you being treated by a psychiatrist? Getting the right treatment ASAP is recommended as things can get out of hand quickly.
