When I get my skin fixed will I stop hating my body?

I have this loose skin all over my body from massive weight loss. It hangs over my bellybutton in a loose flap and it's gross and sometimes if I sweat a lot it gets super gross and sweaty and irritated and I hate it. My body is a prison. I have never felt comfortable in my own skin. Ever. If it were up to me I wouldn't have been made. I'm going to be 39 this year and if it hasn't gotten better by now I don't think it will.
