Hate myself

What are you supposed to do when you absolutely hate yourself and the way you look? I've met someone and we've been talking online for like a month and a half but the thing is: I'm scared to meet up with him because I detest how fat, ugly, stupid, scars and so much else that I am 😔 in fact I actually want to stop talking to him most of the time because of this, there's just too much pressure to be thin and pretty ready to meet him 🙈 I don't wanna be with anyone while I still look like this. Please I just need some help😔
