Thanks everyone for the suggestions. My daughter does already spend three afternoons a week at gymnastics and plays violin in orchestra, and goes to religious ed. one night a week, so she is very involved. However, her depression has made her miss practices, thinking none of the girls like her, it's made her avoid church and religious ed. Some weekends she will leave the house with me and her dad, but if we didn't force her she would sit inside all weekend (lots of sleeping and tv watching).
This morning I took her back to her psychiatrist and got her zoloft increased. She also starts therapy next week. She was crying pretty hysterically this afternoon just talking about her stuff. I am anxious to see if the med increase and the therapist can help her. She's a good girl but she lets the other girls see her weaknesses and she really has a thin skin.
I'll try to find something I can do with her -- there's really nothing she does that I can do, but bowling is a good suggestion.
And thanks,, Maranara, for your perspective on middle school. It is a brutal time for girls.
