Hi D2010,
From what you wrote, it sounds to me like you are feeling angry, hurt, disappointed. These emotions are all totally valid.
Still, you must remember back to how this group didn't feel right to you even in the beginning. You gave it more time, you were patient, you gave it a good solid try. It is natural to feel disappointed that it didn't work out. I know how important it has been for you to have something outside of home. You said you had made a few friends there? Is it possible to contact one or two to meet for coffee? Also, I urge you to look around for another group. It is natural to feel sad and angry, but I hope it won't prevent you from trying again. This is the key... Don't give up. Keep trying, keep looking, never stop seeking to do that which you enjoy. Sometimes it takes three tries, sometimes four or five.
