Could it be psychological?

Currently I’m stuck 10 hours away from my family in a place I’m not happy in, and I’ve been doing okay pretending I don’t hate it here up until this weekend when my work started trying to take advantage of my kindness and make it impossible to see my in laws who are coming to visit next weekend. It feels like that was just a nice big reminder that I hate it here. And around that time (like a day or two after) I started having some stomach issues... I feel nauseous and bloated and my stomach just doesn’t feel good and I’m wondering if it’s actually my stomach hurting or if it’s a psychological reaction from being so unhappy, but stuck here for more than a year longer. Thoughts?
