I completely relate to experiencing high impulsivity, including hypersexuality. I know this is much easier said than done, but please try not to be so hard on yourself. When manic, it is very hard (even impossible during full-blown episodes) to stay grounded and continue to make healthy decisions. The good thing is that you recognize some of the signs within yourself during this time, which is a step towards addressing it.

I constantly put myself down and need to learn self-compassion. One thing I do know, is that we are our own worst critic. (((Hugs)))
I hope you find relief soon.
