Why do I care so much about my image?

Okay, I'm going to be honest, I worry about my image everyday. I worry about fingernails & toenails not being cut (I cut them). I also have to put lotion on my skin and I always have to wax my mustache (it's gone). I also have to trim my pubic hair. I'm always obsessed about weight. Why am I like this? Is it normal?
