Depressed lover!

Hi, my boyfriend is lately REALLY depressed. He says he always feels this way but is really good ay hiding it. The thing is, he thinks hes fat. Even though I've assured him hes not and it wouldn't matter to me even if he was he stil gets depressed and even talks about suicide. It kills me to see him this way but theres nothing I can do any compliment I give him he brushes off and says I'm just trying to make him feel better.
Is there something I can do besides expensive drugs? How can I assure him hes attractive? Tweet
