Bri, it sounds to me like you hate UT or just school and not the profession of veterinary sciences. Sometimes a school isn't a right fit for you. But you only have these two years left. See about tutoring and other ways to get the work done. Ask your professors and their graduate assistants. Pick a better graduate school. Make sure it is a fit for you.

A lot of times these programs are tough because they want to know who really wants to do this.

I take it you are working while in school? Find out what you can do to make this easier on your self. Many doctors are several tens of thousands dollars in debt when they graduate. Sounds obscene, but that's the way it is. But vets make good money. You can get it paid off.

Wishing you luck with your decision.

Note: I almost quit college 2 years in and joined the navy. I changed my mind and I don't regret it. I'm doing what I'm meant to do.
