My son thinks he’s ugly and his actions are beginning to disturb me.

I have a 19 year old son who’s very self conscious of his appearance. While I honestly don’t see a problem with him at all, he’s got nice clear skin, excellent teeth, he’s fit, and his has a great face, I can understand him being a little hard on himself about his looks. It’s normal for teenagers to worry about their looks, and god certainly knows I was worried about what other people thought of me when I was his age.I respect my son’s privacy so I don’t often go into his room. He usually has it locked so I can’t really get in there unless he lets me in anyways. However, yesterday he went out with his girlfriend (another reason I can’t believe he thinks he’s ugly) and I decided to go into his room to put his backpack and laundry basket away. He broke his mirror. From what I can tell he must’ve thrown a coffee mug at it recently because the room was still a mess. He’s never been that...emotional/rash before.I got worried so I went looking around and I found that he has literally BURNED himself out of almost all the photos I have of him!!! It seems like the only ones that he hasn’t burned are the ones on display on the hallway! I knew the photos were missing but I just thought maybe we put them in a photo album somewhere. All his old school ids and old drivers licenses have burns where his photo should’ve been. Photos of him and his girlfriend going out on dates (she uses one of those Polaroid type cameras that print out the picture immediately) have only him burned out of it. Even his PROM PICTURES!! Even pictures as a CHILD!!I don’t think I’ll ever be able to get any of those pictures back!! I’m so angry at him those were my memories too! What if he gets in a car crash and dies and I don’t have anything to look back at anymore?! What am I supposed to look at when he moves out of the house and I’m feeling nostalgic?! At least with the prom pictures maybe I could ask his girlfriend to scan her copy but I’m just in shock. Maybe I can get some of the childhood ones back from out old laptop but I can’t believe he’s done that. I don’t know how long he’s been doing this. I’m ashamed I never knew it was this bad. He’s made comments on how he thought he was ugly but I never knew it was THIS bad. I don’t know what to do. I don’t know what to say to him.
