Maybe it's time to invest in a good humidifier (buy/rent)?
Maybe a bit smaller, but you've got the idea:)
If you want to pass that one, maybe it's time to wash your clothes and set up a drying rack in your room and lay out damp clothing to dry overnight. You'll save energy by not running the dryer, but adding more moisture to the air, all while adding the fresh scent of laundry to your room. Or you may decorate your room with bowls of water (place a few around your house and the water will evaporate into the dry air). Also don't forget to drink a lot of water.
