this is a terrible mental disorder similar to a cancerous ocd that affects 1-2 percent of the population. I always feel that I am a walking monster but I rarely ever get other opinions of what I look like.
yeah it is horrible, I've had it since I was 19 and it had ruined my everyday life, all I can suggest and I know its gonna be hard as I can't even take my own advice is get help fast as the longer it goes on the harder it is to get out of the routines.
Aww, you're not ugly at all! It's a pity some people feel this way when they're really quite attractive! I hope life gets easier for you and I hope you find some help with your problem =] Best of luck.
