Well, first off, pay off as much as you can to get it under the max, and then set up a system where you are paying the minimum monthly amount - if you can do this so that it pays automatically, so much the better. Once you've done this, figure out what active steps you can take to get money to pay off as much as possible. If this means poker BR, then so be it - bad credit card debt is too dangerous to fuck around with.

Getting this sorted has to be one of your top priorities - at the moment the sum isn't too big, and your credit rating isn't going to be too badly affected. But it does need to be sorted out ASAP. If this means begging to your mum (or taking a bar job) then you've got to do it.

Good luck.
