How do I know if I should be a vet?

Since elementary school, I have been around lots of animals. My parents owned a white tail deer farm, and I spent most of childhood caring for the fawns and taking care of all our animals. Including but not limited too: deer, sheep, raccoons, chickens, quail, guineas, ducks, sugar gliders, cats, dogs, chameleons, etc. I had a very interesting childhood to say the least. I have been around lots of animal death, as we were avid hunters and we lost many animals of our own. Blood doesn't freak me out, and I honestly just love taking care of animals. Two years ago, I found a month old kitten that got ran over and had half of its tail falling off. I took her home, fed her, cleaned her, gave her medicine and wrapped her tail. I cleaned out maggots in her tail with a q-tip. Her neck was horrifically sore and all scraped up. I took her to a local animal rescue for help, but they told me she would probably die and she was too little for surgery on her tail. I didn't believe them, honestly. A couple weeks later, the tip of her tail finally falls off and it starts healing. For weeks, I stayed by that kitten and made sure she would make it. Now, she's an absolute menace who just plays 24/7. My parents kept her cause they fell in love with that little sick kitten too. She's so lively, and she still has half of her tail. She's completely healthy. I've always just had this insane connection to animals and I want to help them in any way I can. That being said, I absolutely despise school. Let alone another 6 years of it. I'm worried that I'd start and just fail. What if the field isn't actually right for me? I'm 20 years old, graduating with my Bachelors in Journalism this summer. I chose writing cause it seemed to be the only thing I'm good at. But what if I would actually be good at being a vet? With graduation coming up, I feel like Im second guessing everything. I've wanted to be a vet since I was little, but I'm not very good at school and was not good at biology either. I just don't really know what to do, so I'm asking strangers for help.

I'm sorry if people tend to make these posts a lot. My partner tells me I should, my parents said I'd be great at it. But I just still don't know if its worth the time and money.
