I think some bipolar episode behavior can be far from positive and hurtful to others. I don't believe that that makes us bad when we're in episodes, but the behavior is negative. In this case, it necessitates proper treatment. If we choose not to at least TRY to curb such negative behavior, then I see that we would indeed be at great fault. We must be held accountable in some way shape or form in cases where effort would help, but we don't make it. Of course I see undiagnosed people who totally lack insight as "yet to be clued in" that something is wrong. Unfortunately, many of us must suffer consequences for that to happen.

Your sister's feedback sounds helpful in that she is cluing you in that your bipolar-induced behavior is dysfunctional and/or hurtful. It seems like you recognize that, and that's very good. I'm glad you aren't angry at her in response. However, I also hope that if you put in a great effort to improve your situation that she will give you credit for that. Open conversation is good.
