Have you ever heard of this program?

Summer Institute for the Gifted?

Maybe if she went to a program with a larger pool of kids she might find a kindred spirit or feel less like an outsider.

I would wonder if it just a teenage thing to say she "doesn't trust anyone anymore" or if something happened or is happening with the dynamic of the kids in the new grade. I've known three different moms, so far, with daughters who've been friends with certain girls and they "turn" on them or in one case, our neighbors' daughter was the one turning on another girl (per orders of the "leader" of the new group). All about that age, going from middle school to high school or in one case from elementary to the middle school.

I guess you hear so much about bullying lately my mind just went there as a possible reason she says she doesn't trust anyone anymore.
