I think this insight is right on also. Stressful things surrounding us are one of the worse things that trigger the not eating in the first place.....I always got sick feeling when there was fighting with my parents....& it wasn't something that could be stopped......the driving force to my not eating.....then I ended up in a bad marriage & when the rest of my life fell apart....eating was the first thing to go....from the stress & it not making me feel good so I had no desire to eat.....but it was also about the only thing that I was in control of at that time.....& I was in my 40's when that happened the first time at a major level that was dangerous to my life. Before the stressors came like waves & so did the eating.....but before the stress never lasted long enough for the weight loss to be dangerous......several times since in my mid 40's stress has continued long enough that it has made a huge problem with my eating......

Maybe if you get out of the house when you go to college, it might be a good step away from the stress in the family & better to get control over YOUR OWN LIFE.
