It's a fact of life you'll have to consider so that you can come up with healthy ways to cope. Vet school is hard, it's draining, and it's mentally and physically exhausting.
Yeah, I've been working for this my whole life and I consider myself SO lucky to be here and getting a chance to do what I love but when I have to perform CPR on 1-3 patients a day for a couple weeks straight... that's draining. When I still have to be fighting and working this hard, and ignoring whatever life actually throws at me, it gets me down. Once you hit clinics, you're expected to basically give up your life because, well, you're in clinics. Someone hit my car in the parking lot last week and I have to go and get the door fixed/replaced. When am I supposed to find the time to do that?
