I want to help but he blocks everything out?

My best friend's boyfriend has just now started coming to a Christian youth center and we have devotions. In devotions we pray for help. Well last week he was crying and i asked if I could help him and he said, "My pain is mine and mine alone." It really scared and upset me because he was blocking every one out, even his girl friend. I was wondering if i should just leave at that or if i should really try to help him more.
