I am so sorry for the both of you to have to experience this. I myself had a very rough group of girls that made things very hard growing up. There is a great book series called ” All things guy.” It is actually one of the first in the series called all things girl. The wesite is http://www.atgseries.com. It stems from the all things girl program but you can find the all things guy in the books section. Basicly it is a book to help teach your son to always remember that he is royalty. That he is the son of the King of Kings. It also has pratical advice to teach young kids how to make ” good virtuous” friends, and build confidence needed. I will say a prayer for your son, and hope that this information may be practical and spirtually helpfull.
