You should talk with the principle and school counselor to see what the next step will be for your daughter to return to school. If you don't feel that the school is addressing your daughter's concerns then you can go to the school board. Ask for a copy of your schools policy on bullying.
More importantly talk with your daughter about her thoughts of suicide. Please tell her that suicide is not the solution to her problems. Help her to come up with a safe plan for action if something like this happens again in the future. Who she can talk with, and how she can keep herself safe.
