I had this poll up in my server a while ago, and those who voted (sample size only 12) overwhelmingly believed that most 4 digit (and better) players are depressed.
Transcription of the poll question: "This is an old comment -- but this phenomenon seems like something that would be consistent across time, since it's about the nature of the game. Do you think this is true?" (9 of 12 voted that yes, this is true)
Transcription of the attached image (the "old comment): "i feel like the majority of top 10k players have some sort of depression because osu is a way to relieve stress from life and stuff. i'm glad he's doing stuff though he seems like a really good guy"
My personal experience doesn't really align with this (there isn't too much correlation between how much I play osu and how depressed/down I am feeling), but your viewpoint is certainly not rare.
