Oof, sorry to hear about the TBI, that definitely doesn’t help with symptoms. It sounds like you recognize some of the red flags in your behavior. I don’t know you, but isn’t it possible he’s worried about you and frustrated? It’s mentally and physically exhausting caring for and getting help for loved ones (my dad has dementia, it’s tough). Just be careful with yourself. Manic states quiet the analytical centers of the brain and limit meta cognition. My friend didn’t realize how illogical and destructive he was behaving until he came down, it may be the same for you. I’ll just reiterate my urge to be honest with your doctors and seek treatment.

Just like with physics, “what goes up, must come down”. I’d hate for you to be ill prepared for that moment.
