Gracie Problem Going Back To Class

Grace is having a huge problem with going back to school after the casting. She started this around 3 weeks ago. She cries and hangs on me in the room at Childrens harrassing me constantly. She wants to go home and stay home. She doesnt like when the kids turn around and look at her when she comes in. She doesnt know where she is supposed to go. Etc etc etc.
I hold strong - mostly because I have to get out to class at Waubonsee by 12:45 or I get points docked off my grade - and she goes. But its very wearing after a while to listen to her.
