Help with a friend who has problems and doesn't want to get help but i know really needs it

So I have this friend who has night terrors and he barely sleeps because of it. He's also trying to starve himself because everyone he knows besides me hates him and it's gotten to him and now he's afraid that if he tries a site like this everyone will hate him like everyone he knows (besides me). I told him that if he ever changes his mind about wanting to get in contact with people who understand what he's going through better than I do, I would always be up to finding him some sites to talk to people. He also thinks that anonymous sites like this won't work and that they've never worked. I want him to have more help that I can give. He's even fallen for me because I'm the first person who's actually truly cared for him in who knows how long even though he knows I'm taken which my boyfriend doesn't mind because he knows id never cheat which I will never do but still. I want to find ways to get him more help and show him that not all anonymous sites are bad.)
