Years later, seriously embarrassed of self harm scars

I am cursing my teenage self for being so stupid as to self harm on my arm, creating scars that will be visible forever. I HATE when people stare at them - not that I blame them. There aren't a ton and they aren't super visible but in some lighting they're very obvious because they're slightly raised. I'm in my 30's now, I have a kid, I just feel fucking ridiculous having self-harm scars and I don't want to ever have to explain them to my kid but I know I will have to someday.

I will always have to cover up in a professional setting because it probably looks ridiculously unprofessional and pathetic to have visible self-harm scars as an adult. I wish my idiot, dumbass past self would have thought of the consequences. They scars are too old now to do much about them so I just have to deal with it. I sometimes fantasize about getting a tattoo to cover them up but I wouldn't like that much better - although at least it'd be socially acceptable.

I certainly wouldn't judge anyone else for having them but I feel so ashamed of myself.
