If you personally guaranteed the SBA loan, then you are still on the hook personaly, if you put the LLC into bankruptcy. Same goes for the credit card.
If you declare personal bankruptcy in addition to the LLC, then your assets, to the extent that they are not exempt, will be subject to liquidation by the bankruptcy trustee.
Unless your loan was "collateralized" by something that could be sold to get the lender its money back in the event of a business failure, then you signed a personal guarantee -- you don't need to look for it -- that's just the way SBA loans work -- no lender would give you the money without the guarantee or collateral.
