Having a lot of the same issue right now. Wanting to apply to grad school, have been in touch with a couple of PIs and whatnot, but am terrified that my vet school grades will automatically kill my chances at it despite having done well in undergrad and having a publication and some conference presentations under my belt. Ugh.Making decisions about the future is hard. Ugh.
I feel you. I hope your path becomes clearer soon.
