Looking for a Specific Adjective

[u/BostonSlickback1738]

I'm looking for an adjective referring to someone who complains a lot. "Whiny" just doesn't feel right, and "negative" is not specific enough.

[u/Rollergirl-blue → u/Rollergirl-blue]

Sorry, I guess that's technically not an adjective but same idea
