Your plant looks like it can't handle it, as well.
Get a dehumidifier and stick it in there with them.
You could also defoliate any shade leaves that are over bud nodes to help decrease relative humidity.
If you don't have good air movement already, add a fan. But, don't hit any of your plants with direct air from the fan! It could cause problems that are easily avoided.
Get her stress level down and she'll start thriving again.
I hope this helps.
Good luck!
