I feel disgusting

I don’t know what to do anymore I feel like I’ve hit rock bottom , I feel so gross In my own body I’m paranoid 24/7 , I have bad scars on my arms and thigh I can’t wear anything that shows them even in this heat, I feel uncomfortable when getting intimate with my boyfriend I feel like he don’t like them and he’d prefer me without them or a girl who don’t have scars and I just want to cry because I feel like a disgusting mess and I feel too scared to rant to anyone about it because they might not understand with my mental health and my past it’s embarrassing I want to just chop my limbs off and start again 😞
