Hi Bear, just curious, are you trying to understand someone's behavior as it relates to you, so you can make decisions?

Are you trying to find a label for someone to give yourself validation or peace of mind?

I think the only way to really know is for an official Dx by a qualified MD/Clinician....sometimes those can be off the mark, but better to not speculate.

Good luck and best wishes

ps, many women could be labeled emotionally "unstable" once a month...
