It's not a weird issue at all. A lot of self-harmers struggle with body issues especially by self caused scars. I know I do.
[trigger] I compulsively scratch my face. I have been trying to stop for many years, but it is a deeply ingrained self harming/ self comforting grounding behavior. My skin on my face looks acne ravaged which is only part of the story. I don't wear make up because it bothers me and my tender, inflamed skin. I break out with zits even at 36 all the time. [trigger]
I can't even walk near a cosmetics counter. They pounce. I am horribly self conscious about my appearance. Here are well dressed, coiffed, perfumed women who feel completely free to critique me and my appearance. They tell me to buy hundreds of dollars worth of beauty products and then I'll look good. Thanks. That really makes me feel terrible. Particularly because I know, no cream is going to make 25 years of damage miraculously vanish.
I was trying to say something positive here about living with our scars, but frankly, I lost the energy.
