My dog is really old and he got very sick last night. I spent all night at the emergency vet with him, and I am so worried and exhausted. My HESI exam is in three days, and I have not studied at all because I have just been sitting here with him. I feel so guilty for even thinking about a test right now, but I also know I can't afford to reschedule. I was so heartbroken and torn that I even had the thought that I should pay someone to take HESI exam for me. What would you do in this situation?
