I experienced the same thing. Since I stopped, over two years ago, I've often found myself turning mirrors round so I can't see myself. Lately I've been getting really depressed again and have found even the thought of having to look at my scars again makes me feel so ashamed.
Anyway. The scars never made me stop as they were nothing compared to the emotional scars I carry.
