I feel so horrible every time I see my own arms

I haven't self harmed in like couple months, because I've finally been able to realize that self harming is not a good option. (Unfortunately my mind has decided there's only two options: Dying, or unfortunately, living)
Anyways, my self harm used to be so bad I used to need stitches all the time. Like once I was in the bathroom at the hospital and I snuck a blade and I knew I had to be quick and legit in a matter of less than 30 seconds I cut so much and so deep that I needed 83 stitches. And that was 30 seconds. Anyways, my self harm days are over. But as you can see, obviously since I needed so many stitches all the time I have horrific scars. And I mean horrific. I'm 15 and my parents want me to get plastic surgery for my arms like whaaaaaaat??????
Like I honestly don't know if I'm ready for that. Plus I would have to live with the fact that my arms are "fake". I wish I had parents that would tell me it's okay and I should accept my body and be brave and wear short sleeves and not give a **** about what people think and just go out there and do my own thing. But my parents are actually telling me to keep hiding it and that I can never show anyone my scars because it's embarrassing. Sometimes I even ask if I can just wear even like a shirt that goes up to my elbow and my parents said that people will think bad of me. Like why are they trying to protect me? I did this to myself???? And I just don't know what to do. I hate having these scars and I just want them to Never have been on my arms in the first place but I would feel lost without them and I'm just so confused.

Maybe your parents think seeing your arms is painful for you, and they're trying to save you pain. Or maybe they think it's a trigger for you to want to cut more.

Have you told them that you just want to wear short sleeves and be open about it?

I hope you can work it out. I'm glad you've stopped cutting.

To be honest, it's just that they are protecting themselves. They don't want people to know they have a daughter like me.

How about looking into some legal protection? Even a terminally ill dying girl can refuse a surgery if that's not the person wants to go through, you can not be forced or coerced to have the plastic surgery if that is not your wish. Defying parents is a part of growing up, a mark of a thinking man, it's best to come up with your own reasonings of why you should be able to wear short sleeves, and not everyone think bad of you because of the scars. You know your own progress and you will get wiser and stronger, you may still need a lot of support from your parents, but there's one thing that all of you can not do away with is the trust, in you. Are your parents gonna be the part of the solutions? I hope you can stand your own ground.

I think you should wear short sleeves and not give a **** what people say your parent can't force you to wear long sleeves no matter what they tell you. Your right its probably more about them than you about wearing short sleeves. But I also understand why you listen to them to keep the peace and not rock the boat. I have a good amount of scars too and you listen to that inner voice tells you to rock short sleeves. If someone ever asks just make up some crazy reason for your scars like "You never want to interrupt grandma while she is knitting." Be your self and show your arms of or not if you don't thats okay too. All I am saying is do what feels right to you and not to worry about what your parents tell you. Stay strong.
