My job is making me sick

I currently work in a vet clinic and have been here for six months. Long story short, I was hired right out of school and have been working for six months. All was well at first but lately I have been feeling like I just want to leave sooner rather than later. We had a tech leave so now we are short staffed and I am under pressure to get caught up after months of being on the sidelines. I have started to feel sick on my way into work. Last week, the anxiety and stress was so bad that I threw up. Even now as I write this while waiting for my shift to start, my stomach is all twisted up and I feel shaky. I have never had a job that made me feel this way so I don’t know how much of this is me being stuck in my own head. My husband and I are moving hopefully in the next few months but I don’t know if I can hold out that long. He is a disabled veteran and we do have an option of me being his caregiver where I can be paid a stipend that equals to the same amount I make now. So I won’t be without income. I don’t know if I’m here for validation or permission to leave, but any advice will be appreciated
