Noooooooo, get rid of it, seriously.

I am 22, I have had 3 cards since 18. I am in 6G's worth of debt, and I have just paid my last bills. The cards got cut up a year ago. I will still be paying if off in 3 years time. This is leaving me with fuckall money to spend on myself. I have got 3 jobs to try and clear my debt.

Get a debit card instead, its still plastic, and is still spendable, providing you already have the money.
