However, here are some proverbs that touch upon the idea, which you could adapt to fit your situation:
* "Between a rock and a hard place": This proverb describes a situation with only difficult choices. You could apply it to a scenario where both options are undesirable.
* "The devil you know is better than the devil you don't": This proverb speaks to the fear of the unknown. It could relate to a situation where both options are bad, but one is at least familiar.
* "Damned if you do, damned if you don't": This proverb directly addresses the dilemma of being caught between two unfavorable choices.
You could also craft your own phrase using existing proverbs as inspiration:
* "Caught between a bad rock and a worse hard place."
* "A double-edged sword, both sides dull."
Ultimately, the best way to express the concept of having two bad descriptions depends on the specific situation and the desired tone.
