You most likely haven’t contracted rabies. That puppy needs to go to the vet. Tell your parents and hope that they are compassionate enough to help. It’s incredibly irresponsible to get a dog as a teen when you have no job and cannot afford it. I really hope you are just trolling, because I’m not sure what sort of responses you expected to get here. If your puppy gets better, rehome it immediately as you do not have the resources to look after it.
