how can it be your fault if your dog doesn't want to eat :( taking the dog to a vet would be appropriate, your dog will start eating again and your mother will realise her mistake
hope you are okay, I know it's a tough time, people are treating you like this while your dog is sick, been through that
I am sorry about that Riri. It seems you really care about your dog and hurt by what your mum said. Is it possible to take the dog to a vet?
Just hang in there do your thing make yourself feel better, and the best way to deal with relationship issues is with a relationship therapist. It's the best way to deal with this situation. Also take your dog to the vet if you can, or there are usually groups in fb in all areas usually, that are all about helping animals in need, maybe someone could help you there. Hope your dog gets better, and that you stay strong.
