Um, yeah. Lol.
The big one for me is gender dysphoria. Being trans has pretty much destroyed my life.
I'm like the opposite of you behaviorally: I hate my body so much that I refuse to look at it at all. Or to let anyone else see it. I never take pictures of myself, I never share them with other people, and I would never look at them to pick out my flaws even if I did have pictures. I used to keep my mirror covered so it wouldn't upset me (but I can't do that when I live with other people, so I just don't look at it). I'm unfortunately extremely aware of my flaws because you can't always avoid seeing a reflection of yourself or looking at body parts. There isn't a single part of my body that I like and that doesn't upset me. That includes the sound of my voice. I won't do either voice or video chat, even with my best friend. I only do text. I wish I was invisible so that no one could see me when I leave the house. I've honestly never met another person with a bigger problem with their appearance. But I am actually really ugly, it's not BDD.
I got bullied a lot in high school, because I'm kind of effeminate, and back then being queer was really bad. I got beat up a couple times and got threats constantly. So now I have a phobia of people (like a phobia of spiders) and can't be around them without a lot of anxiety (that's different from social anxiety, because I'm not actually concerned about other people's opinion, only their potential for violence). I have a really bad startle response, bad insomnia, terrible nightmares which I get almost every night, and sometimes even "imagine things" (like I was convinced for like a year that I had a giant beehive in the ceiling of my bedroom). My therapist thinks I have complex PTSD, though I don't think I've actually gone through anything traumatic, it's just that I'm genetically predisposed to anxiety (my mother and all my bio sibs have anxiety disorders, two of my brothers have schizophrenia).
I also have several phobias (bears, spiders, heights, lightning). I'm also a hypochondriac, which is on my medical record now, so doctors are always really skeptical when I bring problems to them (and tbh, most of the physical problems I have seem to be psychosomatic/autoimmune responses, like randomly swollen glands/fingers, rashes, etc.). I have a bunch of other physical problems (vertigo, migraines, ulcerative colitis) but this is about mental disorders.
I also have OCD about violence (murdering people, killing myself, being killed by other people). It used to be pretty terrible, and I almost killed myself to make it stop, but I'm a lot better at managing it than I used to be. I can mostly move past those thoughts fairly quickly. But it's a problem if someone approaches me IRL and I get a sudden thought that they're going to kill me or something. It makes it hard to be anywhere where there are people, because the OCD feeling feels so bad. It makes me feel sick and crazy.
I've also been borderline suicidal (or actively suicidal) most of my life, so I guess some people would call that depression. But I'm too anxious/afraid most of the time to feel "depressed" so it doesn't really feel like depression to me. I think it's just a reasonable response to my problems, since I'm part of a hated minority, in constant psychological anguish, and really poor and will probably be homeless soon.
I probably forgot stuff, but it's hard to keep track of it all. My life is a living hell.
Beauty isn't everything. It's the only thing.
