What do I say to people that ask about my scars without making them uncomfortable?

you can say whatever you want the way you want. there's no specific way to say something to everyone. people are different. so each one of them need a different talk. the important thing is you feel comfortable when you tell them.

Tell them they were mistakes you made in a moment of hate or hurt if you made them on yourself. If you were victim of something, tell them they're memories of an experience that helped you make who you are. Deep thoughts, but they work..

Scars remain to remind you of the strength of will you possess. Without being too discreet, you could inform your askers that you're thankful you carried yourself through your hardship(s).

It's not always a good idea to be totally open about why you have scars, but if people are genuinely curious and you're comfortable talking about it then it's fine to say why you have them. Another good response is to just tell them that you're not comfortable talking about why you have scars and leaving it at that.

I don't think it's 'what' you say as much as it is 'how' you say it. I think people tend to feel uncomfortable when they know that we are uncomfortable talking about it. If you truly are uncomfortable, then just let them know that it's a topic you don't really like to discuss, and I'm sure they'll respect you enough to breeze past it. But from your question, it sounds like you don't actually mind sharing about your scars, so perhaps look inward for starters - meaning, ask yourself it it's really something you have accepted, and are moving on from. It is nothing to be embarrassed or ashamed of, so you don't have to insinuate those things by your tone. You can just state your past as a matter of fact - which it is - and help them understand what stage of progression you are at now.

you can give them the true answer or you can say that it was due to some troubles of the past and these are my victory marks that show I made it. Or you can make up a constant excuse and stick with it.

I was in a bad place once but I got the help I needed and figured there is more to life I'm glad I got the courage to ask for help

I would say that I was going through a hard time in my life and it was personal. I feel like they would understand.

Explain to them that you've been through a rough time in your life. You don't have to go through the details if you don't want to. I'm sure they'll understand.

You should say that they are your mistakes and that you learnt such great lessons from that experience
