I have a few acne scars. I obsess all day about what I look like with every possible lighting situation. During each day, I am constantly thinking about what my face looks like in that situation, especially when under direct lighting, or angled lighting.
I think that you are just self-conscious about the scars. You know they are there, but chances are others dont notice at all. I would just focus on the qualities that you have that you know are good. Know that you, like everyone else is unique and special. Stop focusing on that one thing and know that you notice it because you know it is there, others dont.
hmm have you looked into body dysmorphic disorder at all? i admit i dont know much about this but i do know its to do with obsessing about how you look and how you look to other people. may be irrelevant but anyhoo
