I just got stood up AGAIN

This is the seventh time. I don't know what I'm doing so wrong that all guys I'm into decide it's not worth it to even show up to ONE date. I think I must be completely disgusting looking or maybe I have no personality. I've even been told by one of the guys that stood me up that "no one would ever want to go out with something so ugly". I keep trying, and when a guy asks me out I always get my hopes up and the get STOOD UP AGAIN. I am already a depressed piece of garbage and constant rejection isn't helping. I think I am becoming suicidal. I just want to die. I just can't keep being lonely and alone and miserable. I can't.

EDIT: Only one person I was talking to was online. The rest asked me out in person.
