Poor Ariel! A sudden change in behavior could be due to a medical illness; for example, if she is having accidents all over the house, that could be due to a UTI or bladder stones. I would take her into the vet in the morning. The vet can do a physical exam, routine blood tests, and a urinalysis to see if there is a medical cause behind her sudden change in behavior. If a cause is found, the vet can prescribe an appropriate treatment for it.
