I have ended a friendship with someone who I considered to be mt best friend. I told her everything; she knew as many secrets as my husband. Unfortunantly, she betrayed my confidence by telling my secrets to other people, and talking negatively about me behind my back. Because of this, I ended the friendship. I am in depression now. I am embarrassed that she has informed mutual casual acquaintances of certain facts about my personal past that I would rather have remained private. Of course, she divulged these facts about me in a dirty-gossip way to cause me as much pain as possible. The strange thing is, I have divulged those same facts on this forum to perfect faceless strangers I will never meet. I belong to multiple social groups where I see her on a regular basis, and I can't avoid her. In fact, I joined those social groups because we were best friends for years, so we joined those social groups to be together, and now I make myself physically sick thinking about meetings where she will be. Part of me wants to go to the meetings and try to get through them and be strong, showing her that I will not stop going, that she will not make me stop going, that she can't hurt me. Part of me wants to stop going to the meetings because I will cry continuously. I would like your advice.
