Thank you for reading my post and for taking the time to reply.
I have tried to suggest seeing a specialist but of course he didn't want to. I will keep insisting though, but I will have to do it gently because having another argument will only push him away.
He's 25, I think has been depressed since he was 18 or so, I'm not sure. What I know for sure is that he won't take any medications. I don't know if it's because he's taken them before but either way that's a no-no.
