In middle school i went through this fake ass depression fase where i would try to cut myself with keys but i would only scratch myself because it hurt too much. Had no reason to be depressed either, imediately got over it in high school.
Moral of the story, get over yourself unless you really have issues
One of my biggest concerns in life is if I'll get diabetes, it sort of runs in the family (no i'm not fat, and neither is my family), the concern is in the checking blood sugar and injecting insuline, i can't stand doing that sort of **** to myself. I can look at people driving a needle in me all day and nothing happens, but when i'm cutting my nails and my nail "sticks" to the side (you know fair well what i'm talking about) i get nauseous when i'm picking it out, even though the pain is miniscule.
