I wanted to be a vet since I was 5 years old. I went to school for four years and got a Pre-Vet degree. I decided in my third year that I wasn't going to be a vet - there were many reasons but I too was afraid that my grades wouldn't be good enough for vet school. My first year I failed 2 classes and redeemed myself after that and did well the next 3, but my GPA wasn't as good as I had liked. I ended up doing something completely different, and I'm glad that I did. If it's meant to be it will be, and maybe you're meant to do something else. I would have never thought in a million years that I'd be a funeral director, but now I couldn't see myself doing anything else. I know that I'm meant to be here. Or all hope is not lost, you just need to, like Kater said, do all you can the next few years in school, do as much volunteer work as you can and keep working towards your dream.

I wish you the best of luck in whatever you decide to do.
