Is it normal insanely insecure of my 'emo' scars

I think the feelings of insecurity are normal. I also think that if/when you find someone to be intimate with in a way that you might start thinking about sex with them that you should share these insecurities with them. I have no doubt that if that person truly cares about you that he will deeply respect you and your body and find you sexy and beautiful, no matter how many scars you have!
