What is it called when people are giving you judgemental looks when eating? [I Anorexia]

I'm not being paranoid because this is in relation to met eating. Wore a right fitting shirt today that made me look a little more husky, I like it but it seems other people do not. So for lunch I had a big Japanese bento box. If people think I'm too skinny they should be happy I'm eating, too heavy, and they should be glad I'm eating Japanese food. Yet instead while outside people just kept glaring at me. I don't know what I did to deserve this.
