Hi @kattytee, this is a good question. I've SH'd on and off for 30 years. For about half of those I hid the scars, wearing long sleeves and pants all through the year because I was ashamed of them. At some point I got over that and started wearing short sleeves. Sometimes people asked - kids often asked - I gave answers that I thought the person could handle, so I told the kids that I had an accident, some adults that I self-harmed, most adults that it was none of their business.
In the last 5 years or so the scars have become much more extensive and defiguring, also less recognisable as self-harm so I've started hiding them again - not because I'm ashamed of them but because people find them alarming. I'm aware that for someone who thinks they know me to suddenly see a massively defiguring scar and the meaning of it can be almost traumatising... and it would be selfish of me not to protect them from that. So I'm back to extreme coverings. It's different - better - than before when I covered though. I'm not ashamed, just protecting others 🙂
