I've read you've been getting a lot of crap because of your weight. I know how awful it feels to be judged simply because you are not a size 4. But you are 100 percent right with your response when you say, "Screw 'em!"
When people think that your size is bigger than your talent, screw 'em. When people talk about your clothes instead of your songs, screw 'em. When people tweet negative crap about you instead of sharing your awesome, screw 'em.
