Who do i call? Or what do i do..?

My boyfriend is really depressed and angry with himself and feels like everything bad in his life(which is a lot of things, even if i already know about everything which i doubt) i want to call someone, like a hotline to ask them what i can do to give him hope. I dont know what to say to him to do this because there really is none since hes going to be sent away soon to live with relatives who live in the middle nowhere. I care a lot . but if you can give me advice, or a hotline to call, or anything thatd be great. His parents wont help, and i dont think he can get therapy because of the situation with his parents
