>>33213541 (OP)Just tell them you're bipolar and tell them what that means, you inform them that every few weeks (or months if you're type 1), that you will get depressive and irritable as fuck maybe even sometimes paranoid. Then afterwards you will be manic and overly energetic or enthusiastic and a bit impulsive.
Tell them it's a mood regulation disorder, it's not something you can control but that you are self aware + open to treating it with meds and/or therapy.
It's honestly not that big of a deal breaker if you find someone who is secure and mature. I've known plenty of bipolar, decent people. Whenever they lashed out at me in anger or got distant or paranoid, I knew it was their mood cycle and just played it patient and kept supporting. It's not that hard
