Any mom's with SH scars?

Currently ttc! However, for about 6 years of my life I was a self harder and have very obvious scars on my forearms. I was just wondering if anyone is in a similar situation, and if Dr's or nurses or even other parents seem you judge you harder for it? Or how you plan on explaining to your kids when they're old enough to notice? As silly as it sounds I'm very nervous about this. I've had people judge me and ask me if I'm stable enough to be babysitting my godson (yes, a random stranger in public) and it really hurt me! I have been clean for 4 years.
