When you are fat, people don't see you as a human. All they talk about is your weight, not how kind or generous you are or some shit. I just thought about some of my memories as a kid and what people said to me.
*I enter to my wrestling teacher's house to train with dumbells. His son is there too. We are alone.*
Him: "You need to wear termal clothes before exercise so you can lose weight"
Me: "Sweating helps you to lose water weight, not actual fat"
Him: "Okay stop eating then"
Or the other time I went to a doctor to get my allergy medication:
Him: "Omg I bet even my adult son is skinnier than you. How much do you weight?"
Him: "oh you are only a few kgs less than him" *starts laughing*
I was just a kid that needed love and attention...
Nobody cares about how you feel, they care about how you look. Nobody gives a rat's ass if you are sad, suicidal, not eating enough and fainting randomly. As long as you are considered unattractive by society, people dont give a single fuck.
