He's going to have a hard time going from China to Canada on his own ...
Anyway, a friend of mine had similar problems.
She tried to kill herself, yet failed at it, and after all, she somehow managed to move together with one of her friends.
I don't know what happened to her though, haven't heard from her ever since.
Nonetheless, if you go to a school or something, try to find good people to spend your time with. I know it's generic and blah, but it's pretty much the best thing you could do. Or, if you can't manage to find something, just take some minutes/hours to relax - Lay in a grass, don't think about anything, just enjoy your little time for yourself (which does not include fapping). Honestly, it helped me a lot when I had loads of problems. Point being, just sit somewhere, turn your mind off, and let yourself go for several hours.
I'm not Christian, so I can't help you with anything else but bad advice.
