I thought the breakers were there to protect the wires....????

If there is 12 gage wire from the breaker to the outlet, then I would replace the GFCI outlet with a new 20 amp GFCI outlet, connected (line side) to the wires from the breaker box, and connect all the loads to the load side of the outlet.

This assumes also that the wires in the box are all ok still.
