Dear Missy,
I feel for you so much. You don't see a way out and every solution seems impossible. I wish I could deliver a moment of clarity for you where you could see the clear path. When your current situation is so unacceptable that you will make it work. For example, you say your cats are keeping you from going into rehab. I'm sure there are several animal rescue organizations that would have someone to foster for you.
My point is, once you decide to end this nightmare you are living in, you will find solutions to all the reasons you have for staying addicted.
I hope you will take this in the loving manner that I mean it. Keep posting here, even if you are not ready to quit. This group will inspire you to make healthy changes.
