Why does my family shove unhealthy food down my throat?

I feel like I'm abused, today they brought home reese's pieces and twinkie's for me, ever since I got braces all they've been doing is shove unhealthy food down my throat 'because it's soft' they think I'm some kind of freak or something, and I'm not gonna eat it, feelings hurt or not. I'm exercising and dieting (5'6 and 108 lbs) and they're only making things harder for me. Any advice?
