I live in FL and the humidity is high as well as the temperature. I tried giving it more sun but that did not help. What can I do to perk up the plant and get it to start growing again? It is 10 years old.

It likely is stressed from the heat. Christmas Cactus do better with temperatures in the 60 to 70 degree F range.
Find a partial shady location out of the heat if possible. Also a tray of pebbles with water can help with humidity and keeping the soil cooler.
