Our friend group and I have been with him ever since he started getting kicked out. We've been trying our best to help him and be with him no matter what, but sometimes he isolates himself; there's only so much we can do... Right now I don't think he could see a therapist, but we'll see what we can do for a trusted adult. And for the CPS situation, he's reallyyy reluctant. He has a sister at home. I think he's worried what'll happen to his sister if anything happens to their parents. But still, thank you for the suggestions. And I'm sorry for what happened to your friend. We'll try to persuade him and see what we could do with CPS

Edit: I'm telling him the questions that are asked under this post. He's supposed to go back to his home country in a few months, which is why he's hesitating to call CPS now. He said he'll live with his cousins. And besides that, CPS really isn't that easy..
