Getting rid of ugly self harm scars?

Please please tell me how to get rid of them. I have hundreds of them on my upper thighs and they are ruining my life. I reject every single guy that I like who also likes me because I feel so unconfident and embarrassed because of them. I will never allow myself to get into a relationship because they are EMBARRASSING and ugly and I hate them so much. They're only on my upper thighs (I still wear short shorts), but there are probably almost thousands of them. When I used to cut (I stopped like 3 years ago) I cut over every tiny part of skin that was available, and even over some scars. How the fuck do I get these off of my legs. I don't care what it takes I need them gone. I have a pretty amazing body and I'm pretty but none of that matters because I hate them I hate them I need them GONE.
