First off don't set unhealthy goals for yourself. If you're going to set a goal make it one that will make a positive difference in your life. Thin is not that kind of goal.

I know personally when I am stressed & bust I have no appetite. Could be what you are going thru. Mid terms & finals were always stressful weight loss times... But anything stressful can cause that.

If it is the start of an ED...STOP!!!! Don't start because it gets even harder to stop after you start that stopping now
