英语作文 to be a vet

want to be a vet, but I get dizzy around large amounts of blood?
All my life I wanted to be a vet.
I'm 14 now, so thought I would start looking into Universities and I've
realized that I can't do much with the grades I've been getting.
Lately, I've been getting all A's on my tests and I'm really excited,
and confident I'll get into vet school. I was thinking of the stuff I
might encounter while being a vet, and I'll probably get a lot of cases
where there are large amounts of blood.
