Feeling “trapped” during my shifts.

I work 12 hour shifts. I’ve tried nights and days but it happens during both. I feel like I’m dealing with some agoraphobic like anxiety. The entire day before, I dread being trapped in the hospital all the next day, getting ready for said shift feels like shooting myself in the foot.

I literally called 2 hours before my shift started the other day and said I had a family emergency and that I’m coming in but I have to leave 4 hours earlier than expected. I immediately felt a wave of relief. I had the best shift ever, just knowing I had some control over the situation. However, I can’t just do that every shift and I’m not sure I’d financially be able to swing 3 8 hour shifts. (5 a week isn’t possible either).

I crave a job where I’m not in the same environment for 13 hours at a time. I’m 39 minutes into my shift and feel overwhelmed with “I need to get out of here”. I’m already feeling the grief of the next two shifts after this. Idk what to do. This is more of just a rant but I’d like some feedback if this sounds familiar to anyone else.
