Genuine question, does having Bipolar Disorder explain / excuse a person being down right rude and behaving badly towards friends? They can be great, fun and really pleasant - like their ‘old self’ before being diagnosed, then there’s a period of being really rude, totally unreasonable and over the top about minor stuff and they expect others to put up with it. I know if you care about a person you’re there for the highs and the lows, but atm it feels like they use their diagnosis as an excuse to say things they wouldn’t have said to friends before.
