Emotionally conflicted student starting terrible habits

Hi MFP,

I have a background a bit different from the typical "not adjusted to college" freshman 15 weight gain. I lived on my own for the past four years at boarding school (high school) and was able to keep my weight in check. That has changed.

Some context:
It has been a month into freshman year of college and I am the unhappiest I've been in years and years (ever since my parents got separated when I was in high school). I went to a quite academically challenging "college preparatory" boarding school for four years, but unlike many of my classmates who also worked their a*ses off and went onto universities of their choice, I was waitlisted at my top choices and ended up in one of my "safety schools". After being devastated, I decided over the summer to accept the situation as it was and resolved to come into freshman year happy, forward facing, ready to do well.

Now:
My self motivated attitude quickly fell short of realities. I do not feel like I belong at my current school, both in terms of my studies and my non-class passions. It has been a month in and after going with it for the first two weeks, I've slipped hard these past two weeks. I procrastinate. I am not at all excited to go to my classes. I do the minimum amount of work. And I've turned to food. The sinful temporary satisfaction of food. Like any distressed eater, I've tried to make that sinful temporary satisfaction last longer by gorging on food alone in my room by the chip bag (literally a whole big bag of Doritos), ice cream, crackers, snack cookies etc. I KNOW that I should stay away from such terrible-for-you junk foods (etc the whole spiel etc) but I am obviously not rational in the mind at the moment. I am on my way to throwing away a first year of college education and ruining any chances of transferring to a better university more suited for me.

To give you an idea of a day in my past couple weeks. Today went down like this:
1) Skipped first lecture class on material I covered in high school.
2) Was in room alone and had to do work that I purposely procrastinated and put off because I didn't want to touch it over the weekend -- so I bought comfort food in the form of a hot bagel and a pastry...
2) Made it through first class. Felt like I wanted a slice of banana bread (which is more like cake) to "reward" myself/keep me going
3) Made it through second class. Bought chocolate bar, another slice of banana bread, granola bar (I guess those carbs are the best comfort emotional foods)
4) Made it through third class. Bought dinner in the form of salad with pasta, some fruit, bag of bagels to keep in room for grab on the go breakfast for the week. (Except I knew even at the time that they wouldn't last me the whole week.)
5) Stuffed myself in 10 minutes with my meal...then proceeded to gorge myself on three of the bagels.
6) Felt so sh*tty that I went to sleep in my room. Just woke up and showered to feel less disgusting. Decided in the shower to come onto this site to at least let SOMEONE know.

I am a short girl whose BMR is only around 1300. I've been gorging on upwards of 4000 calories daily (think an entire container of Haggen Dazs + an entire big bag of Tostitos + jar of creamy dip at 12 midnight after an entire day of eating already) -- I've gained close to ten pounds in the past three weeks. Please help. I know I am not living up to my potential. I did not go to four years of boarding school to knowingly f up my first year of college and eat myself fat. Please help.
