This definitely fits, you don’t need a diagnosis to know this is an issue. Especially if you bothers you. You don’t need someone else to tell you you’re insecurities and intrusive thoughts are valid.

Yes, it sounds like BDD with excoriation (skin picking). I highly recommend seeking a diagnosis and treatment. Skin picking can leave deep scars and make you much more prone to staph infections and other bacteria. Staph scars can be pretty bad. Therapy and medication has helped with my excoriation symptoms immensely, albeit with a lot of work. Nobody feels attractive with red spots and scabs on their face, but especially not those of us with BDD. Getting a handle on my skin picking has improved my condition in general.
