Chiefpilot, the title of your post is telling...things are bad and you need to act now. Sorry but i think things will only get worse. Your credit card, which by no means is your largest debt, is your most expensive debt and in your current situation you are probably barely making the minimum payments.
Use at least 3k of your savings to reduce this, then switch to an interest free one. Its not easy to make changes, but renting out room is great idea, and will give you financial breathing space. I dont think Eirefinq read your post correctly, he thinks your loaded, get a pension, more shares in c.union??? You're young, you have youth on your side, save when you have spare cash. I speak from being in a similar situation, you can go into shock and it takes a long period of time to adjust and accept and deal with it.
I wish you courage and good luck.
