I used to self-harm on my arms and the scars are still there. They've turned white but aren't raised or indented at all. It's been a few months since it happened and I'm getting really worried about them. How long will they take to disappear? Can I speed up the process? I'm NEVER going to do it again; I just want another chance to make things right. I'm ashamed of what I did and everyday I'm reminded of it.
