Give your plant some humidity via misting or a tray of pebbles beneath it filled with water. (Be sure the pot is above the water and can't absorb it.) Also, check that your soil is dry before watering. It could probably use a brighter light situation as well.
I suggest replacing the soil and cleaning out the container. Use a well draining soil such as 1/2 potting soil and 1/2 perlite. You may have some root rot starting.
