A blood test for tick borne disease, and an analysis of your dog's stool are not very expensive, anywhere.
Just to have these two things checked is a lot less expensive than the alternative, which would be allow your dog to die of a disease that could have been treated had you given the medication in time.
I am sorry that I cannot offer you more help but it is important to find out what is wrong, and this sounds like more than your dog being sad because you moved.
Are there any humane societies, such as the SPCA (society for the prevention of cruelty to animals) that offer discounted veterinary care? Most areas do have them, even in Hong Kong, for example. I don't know where you live but if you list your location I would be happy to search for you.
