Self harm scars. Getting married next year. How do I make them go away?? (photos)

I am 26 and before the marks would go away. But last October when I did it, after I cut, the scars got dark, red and raised. I have tried kenalog shots, but it's a small difference it's making. I have got it done twice. I am scared the scars will sink in if I keep doing it, and I have some strange pinkish blue bruising. The scars are 5 months old and I am so desperate. I don't want to have these scars on the day of my wedding. I am not sure to try skin graphing, laser treatment, more shots??
