Is it a mental disorder if I am scared of the inside of my body?

Well, it's hard to explain, but I am scared and paranoid about the inside of my body. I can't look at any part of my body(hands, feet, arm, leg any part of my body) without feeling weird and paranoid about the inside of it. I just always get really scared that my skin is going to break and my insides are going to come out, and even just laying or sitting I always feel grossed out and paranoid about my body, because it's just a organ, it's weird. I know it sounds crazy, but I have a phobia of my own body, not just mine, everyones.
