Hi ~ Have you ever thought about why you do this? What are you thinking about when you go on a shopping spree? Does this make you feel better about yourself, and how?? Do you feel prettier? Do you feel better than others? Do you feel 1st class instead of maybe "coach?"
What triggers these sprees? Do you know? Is it a fight? Something on TV? Is it the way you look?
How do you feel after the spree? Do you feel guilty? Shamed? Disappointed? Upset? Mad?
An addiction is a disease, and can be treated. This must be very difficult for you, because if puts you deep in debt.
Have you seen or talked to a therapist? If not I would suggest that you call and make an appointment with a trained counselor. With a little work, this can be treated!!

Just like alcoholism, you can go into recovery!! Take it a day at a time, and be focused on what you're doing and try to notice what triggers these sprees. I wish you the very best - but please make that call. Keep us posted on your progress! God bless and take care. Hugs, Lee
