I don't know if I should tell him, should I?

My best friend, well we are more than that. But we haven't really figured that out yet, he sadly lives quite a while from me. But anyways, he knows I've struggled with self harm, and I could tell he was sad and disappointed that I ever did it, but recently I've been stressed out like never before and sad and depressed and I did it again, and I want to tell him but I don't want him to be mad. should I tell him even if he might be upset?
