I'm struggling with debts from credit cards and I'm realizing that it will be very difficult for me to clear their balances. They charge me something like £95 only for interests, this is a huge amount for me!!!

Does anyone know what happens if someone with credit cards debts leave the UK permanently without paying off his credit cards balances?
I know it's a criminal offence but I'm desperate to find a solution in a short time.

Thanks!
