I have a friend, he is very intelligent he over thinks everything and it makes him crazy and all thoughtful, he has depression, and depersonalization. I'm his friend and I don't know what to say to him, well I do because I'm semi intelligent that's what he tells me, by my anxiety gets in the way of helping him and I keep fearing he'll rely on me and I'll make his thoughtfulness worse. Any advice to help him with his thoughtfulness?
