I don’t know!😣

So I have a friend who I know has been abused. He doesn’t like to talk about it tho. Anyway he hasn’t been at school recently, I thought it was weird but then he told me (over messages cause he wasn’t at school) that his sister died. I’ve told him that I was extremely sorry, that I’m here to talk if he needs to and if I can do anything to help but he hasn’t really answered. I know he is hurting but I don’t know what to do to be a good friend. I would really appreciate if I could have some advice.

Thanks guys xx
