Self harm

I have self harmed ever since I was 12, I have a few decent scares on my Body.  I have suffered a lot with my mental health having countless hospital admitions. I have currently been really good and haven't self harmed in 34 days! Although I love looking down at my cuts and burns! 
My question is... How can I self harm without it looking like a self harm mark? I just love scars 😍
