According to his own words he bought this snake a week ago from a pet store.... He had the money to buy an animal but no money to care for it a week later. It does not surprise me that other animals you "care for" are "all types of ill". You are obviously abusing your monitor if he has fallen that ill within the week since buying that poor bp ...
Give the animals to someone who can afford to care and pay for them properly. If your finances fluctuate that much within a week you do not have a stable environment to care for multiple animals that require quite specific care.
