College food making me nervous

Opening this with the fact that I dont really think I have an ED but have been really nervous about food recently. I'm also kinda hyper aware of possible EDs because I have ocd and know it's comorbidity. Anyway, because the food at college is so lean that when I travel home or back to college I have stomach issues for like a week. Its to the point that I have had noticeably worse anxiety around food. Especially when I'm nauseous when I get hungry. I thought I was just sick and that was the cause because even when I eat very full meals from the dining hall I still get hungry so quickly and nauseous more often as a response to that hunger. I haven't had ghat as a reaction to hunger in the past. I guess I wanted to know if anyone else dealt with this while moving locations, or if they have had similar experiences, I want to feel less alone, and if any of yall have scientific knowledge I will certainly eat that up ( pun intended;D) also feel free to take this down or whatever, I'm so willing to edit it if this isn't the place for it.
