what can i do?

 after my uncle passed, 4 months ago now a couple days before my move into college, my cousins are alone. 9 months ago my grandfather passed. they both passed in taiwan, my cousins are both in their mid 20s with troubled childhoods. it was devasting for them to not only lose ah-gong but also their dad. my mom texted one of my cousins today, hes the one who is more rowdy and has anger issues, he was in juvy for a bit. i do not get along with him the best, but he is caring and isnt a bad person, just troubled. he told my mom that his brother (my other cousin) started to talk to himself again and that he would play with toys acting like they were talking to him he says that those are his friends, and because there is no one for him they are there for him
