Hey,
You're not crazy, and you're not the only person in that boat. My GPA for the first 3 years of college is a 1.9. Ya. Ouch.
Not to make excuses, but two months after I left that college permanently (they were not helping me try to improve, or see a doctor, or be tested, or anything), I was diagnosed with a significant learning disorder that had not only affected my academic abilities, but had made it so I had no idea how to study.
Since then, I have been taking a few classes, teaching myself to study, and in the past 3 terms, I started to pull all A/Bs. I'm working very hard to pull all As this term, because if I do, I will automatically be accepted to a rigorous academic school with a fantastic support system, and I can finish my degree and prereqs.
I did a lot of researching, poking around this forum, and work - If I can pull a 4.0 for the rest of my college career, a 4.0 for my science and last 45 credits, do exceptionally well on the GREs (I've already started to study), and get a lot of varied veterinary experience, I think I might stand a chance, and I will probably have to apply at least twice.
🙂 So I say go for it if you are really committed! You definitely won't be the only one.
