I screwed up, but I know how to fix it...
If you already looked into the situation then atleast you have a plan. I didn't even think of controlling payments by recycling payments down to my lowest APR.
The $3,500 damage was already done by only making low payments, I carried that debt for over 5 years but got rid of it in less than a year once I understood the game.
I used my lowest to double payments onto the other two cards and dropped good payments on the main card. I talked with the bank that gave me that card, they lowered my APR just because I was on time with payments and I was making large payments (handling the two other cards off it made the amount owed higher).
Crushed the debt really fast and looked good to all three credit companies. But I will add, it wasn't a fun ride, had to sell off part of my game collection and work two jobs but I wanted that $9k debt gone and gone for good.
