I'm so fucking fat

Today I went to hangout with my best friends and I ate so much today...In the car we were talking how I used to go to church at the mall we were in and my bff mentions "Oh yknow my dad saw you and called you fat" I asked for her to explain and she said 3 years ago I saw her at the mall said hi then ran up the escalator and after I left her dad asked her "Why is she so fat?"I felt guilty eating so much that day and learning that makes it even worse. I was 11 years old at the time and thay wasn't even my highest weight so in the small chances I ever see her dad again what's he going to think? I'm so fat its not even funny I'm dumb, ugly, and fat if I were smart I could make up for being fat and ugly but no I'm not. Sorry about the vent I'm about to cry just wanted somewhere to say it.
