I may have left this out in my description, but compulsive spending, or basically doing exactly what you did, can be a symptom of mania. Were you gambling? Or what kind of games. I did that during a manic episode and ran up a pretty big debt. I might advise you to let your psychiatrist know what's going on. Call and tell him/her about what just happened. You don't want things to get worse. Give your credit cards/debit cards to someone you trust. I'm just speaking from experience, I did a lot of damage to my credit rating all because I got manic.

You may be in a crucial stage of a manic episode, so please don't be afraid of trying to get some help for it.
