Does anyone else have a hard time believing someone else when they find you attractive?

I'm talking to a few guys online currently because I'm attempting once again to find love. Yeah I know I'm a stupid idiot for even trying and it probably won't end well as usual but I'm trying. Anyways one guy said I was gorgeous and I about wrote him back telling him that's not true and that he's joking right. I just have NEVER believed anyone who said I was because i myself never feel it. I just have never been able to see it no matter how much I do to myself. I was picked on a lot growing up for my looks and to this day it has affected me.
