Vet bill affecting studying

I unfortunately had to put my best friend down after months of vetrerinary bills. I tried my hardest to keep him alive without him suffering. But as soon as it appeared too much for him I made the very difficult decision to let him go. But the euthansia ended up costing a lot more as I wanted it done humanely and as a student who pays for all my animals costs as well as studying I have been swomped. I only work a part time job so that I can further my education and I would just like to pay the vet bill off so I can focus on studying now so I too can become a vet and help animals like my boy that I had to let go.

I would really appreciate the help as this bill has caused stress which is affecting my university work and I don't want a bill to be the reason I can't afford Veterinary school or do badly in the BSc needed to bridge into Veterinary.
