Q.My Desert Rose
I don't understand what's wrong with her. She was fine a week ago and now this. She is on my dining room table so gets morning sun. Too cold to be outside.

Was it by any chance outside during a cold snap? They can't tolerate any temperatures below 40 degrees F. (4 C)
Another possibility is root rot due to improper watering. During the winter, they should be watered very little while dormant. And no fertilizer. If you think that is the case, quickly repot the plant in fresh, dry cactus soil mix.
