nichole_06_1988 sounds like Jinx really needs to see a vet, she should have blood & urine tests done and a urine culture done as well. This could be a complex medical issue or it could be a urinary infection that can be cleared up quickly, if it is neither and a behavioural issue you will have the starting point with the vet.
Please do not take away the water, cats normally do not drink very much water & can become dehydrated fairly quickly.
Find out if your vet will work out a payment plan, borrow from family or friends, use the credit card.
to Jinx & you, keep us updated on how she's doing
