how do I explain self harm scars to my significant other and or children?

i would explain them that those scars are battle scars from fights that i have won against myself and for my childs i would explain them when they had the age to understand

This depends hugely on your relationship with your significant other and the age of your children. For your significant other I would usually suggest being honest with them, even though that may feel like a difficult conversation to have. For children, any answer needs to be age appropriate - it could range from "they're from when I wasn't feeling well" for a younger child, to a more on depth discussion about mental health and what to do if they ever need help with an older child/teenager.

If you feel comfortable enough with your loved ones, you can tell them the truth. It's nothing to be ashamed of. You can tell them how you felt of how you needed to feel and that's why you have them. When it comes to children you don't need to tell them the truth. If they're not too visible, you can tell them you fell or something, but if they're visible you can tell them you were really sad and this is what happened to you from feeling that way. It really depends on how open do you want to be about it. But I wish you the strength and confidence to wear those scars with love and pride because they're just reminders of how brave and strong you are ❤

If your children are young you can tell them they are battle scars. If they are older you should talk to them about stuff like that one day or another. As for your partner, I recommend explaining it to him. Honesty is keeping every relationship together, just have a long talk with him.

With honesty, expressing how it felt when it happened or how it feels for you having these scars. To the children only if they ask and when they ask. A significant other has to know you and your experiences and love you the way that you are. The children appreciate a lot when you are being honest with them, it creates better bonding and they will seem to understand you more. Also they will gain wisdom by your experience and maybe this will help them accept and learn how to care and love others who have similar experience to yours. Spreading awareness makes people wiser and more understanding.
