Calorie intake for 18yr old active female 5'8"?

I started college this year, and I feel completely junky because of all the terrible food they give us. I'm gluten intolerant, so my main food lately has been frozen grapes, broccoli, humus, A LOT of trail mix, soups, salads (no dressings), and at the end of the day-a ton of chocolate! After being concerned with my nutrition, I started counting through the myfitnesspal app and my normal goal is 1400 calories. I'm also on the triathlon team and I exercise for 2 hours a day 5 days a week (sometimes 6). Is 1400 enough? I normally don't eat that much, but I've found myself getting very hungry and I end up just filling the void with late night splurges of chocolate (like last night, 400cals worth of chocolate covered almonds...)
Also what are some easy ways to get gluten free protein when I don't have a kitchen?
