I agree with bizi that those girls thanking you for the apology should free you now. I hope that if they do not agree to friendship again, that you can simply move on. I know it can hurt, but that's a sad fact of life, in some cases. Buddah1too's reference to the role of apology "amends" in 12-Step programs is just as much for the person with the illness than for others they harmed. The word "Sorry" is significant, but more so is the change in behavior and attitude.

It is difficult when an illness (like bipolar disorder) is seemingly the "bad guy" more than the person with the illness, themself. Mental illness will probably always bring with it stigma because the average person in this world thinks everything manufactured from the brain is conscious choice, which it isn't. Such notions reflect lack of understanding/education about mental disorders, and frankly, simplified and reactive thinking. I can't blame only people without mental illness for unfair reactions to the behavior. Even people with mental illness stigmatize others with the illness, and even punish themselves for having it. It also must be noted that our behavior is not strictly manufactured by a mental disorder. We are still people with personalities and issues who DO make choices. Choosing and sticking to treatment plans, the best one can, should indeed receive credit. Yes, effort counts. But again, to some, it's not enough. Grudge holders are very numerous in this world. Lack of tolerance is sadly commonplace. People divorce at high rates. Friends become enemies or reject. It's not just happening to you, or me, but pretty much everyone on earth, at times. C'est la vie!
