Please help me I don’t know what to do

Ari

So I have multiple scars on my legs and butt from mosquitoe bites ( I live in Minnesota) and acne. Ive been dating my boyfriend for 3 months now and I still won’t let him see my body because I’m really scared it’s been like this since sophomore year and I’ve graduated high school already. I don’t know how to fix it and I don’t know what I’m doing wrong it looks horrible believe me. I haven’t worn shorts in public in years because of it. I don’t know what I’m going to do. I’m scared 😟
