I don't have BDD, but it definitely sounds like you might have it. I don't exactly know the exact treatment for Body Dysmorphic Disorder, but I'd imagine it would be along the same lines as the treatment for regular OCD (which I do have, unfortunately) b/c it's classified as an Obsessive-Compulsive Spectrum Disorder (OCSD). I don't know if SSRI's would work b/c they don't typically work for anorexia nervosa, another OCSD, but it wouldn't hurt to ask a psychiatrist. Also, Cognitive Behaviorial Therapy is probably the most effective means of treatment. If you have any questions, feel free to ask. God bless!
