Sierra--Hello Everyone

Options
Hello everyone,

My name is sierra I'm 19 5'5'' and I'm looking to lose 20lbs. So far so good, I've lost 4lbs so far and I'm really determined but one thing is holding me back and that's food. I know it sounds silly but I'm a college student my my diet isn't the healthiest so dieting here around all my friends, the fast food, and the fast food disguised as the cafe food is hard. i think I'm just looking for ideas to help keep me full throughout the day on a budget and some encouragement.

Thanks :)
