11yr old grandson anger and depression

I see him once a month for visitation and just recently he got so angry after I disciplined him, threw a chair and hit the cabinet and screamed "everybody hates me" where he is staying he said that a 14 yr old cousin is always hitting him and his mother will not do anything about it, she has many boyfriends and now she is pregnant and my grandson says he does not want to live with her and he has so much anger inside. What can I do to help him?

Perhaps a good idea to speak to his mom as she can change things not you, what discipline method did you use, he was very upset to throw a chair it certainly seems there is a big problem, maybe he will need some counseling,find out more about what he says regarding the cousin ,bullying needs to be stopped , he is only 11 year old he needs protecting... How about you speak to the cousins Mom or ask your grandsons Mom to speak to her. .
