What should you do if a friend were to confide in you about abuse at home?

Abuse is really serious, especially one committed at home. I'm really glad your friend confided in you, and you should understand that he/she is going through a difficult time. School counselors are always a good idea, and definitely your parents. Your friend might be worried about his/her parents/guardians/whoever getting into trouble, but he/she should know that it is not their fault and no one deserves that. I hope it gets better. :)
