I wish I had known not to worry too much.
While it is important to pay attention to your snake and see what it is doing, you shouldn't freak out too much. I used to stay up at night when I saw that his humidity was at 61% or more and tried my best to lower it. I even called a vet because I was afraid my ball python had IBD.
It is important to know things and look after your ball python but not everything will kill your snake.
By the way make sure to put your snake in quarantine for about two months (normally I'd say three months but since you don't have any other reptiles). It is important to make sure the animal is healthy before putting in a terrarium. Look for snake mites, possibly do a fecal (I know people on this forum don't agree with this but I learned that it's better to do one if not even two) and for symptoms of illnesses.
