Preface: idk what I'm talking about, don't take my advice.
In general, pay off highest interest first, by throwing extra at the principal when possible. However i assume there is little to no extra in your income, even if you take a hard look at minimizing expenses while in debt. Some of this is basic finance literacy, but surely some people need a reminder to really think of sacrifices for the sake of saving - if you're making vehicle payments or can downgrade transport costs, eating out, subscriptions, have any options to reduce or share housing costs, etc.
30k is probably not worth the long term impact of bankruptcy.
Assuming you have no savings? CC companies can sometimes negociate lump sum payments at a loss of it avoids collections and defaulting payments.
It could be worth talking with a local bank or credit union about consolidation, if they are able to offer you better rates than the CCs, and consult with more than 1 if possible. In the past it was not uncommon for consolidation loans to offer better interest rates than CCs, which are often among the highest rates of any legal (non shark) loans. If that's available and at what rate depends on your credit score.
