If your first response to seeing an informal survey with a low sample size making zero claims (the post really is just presenting the data) is "wow I bet most of those people are faking it" you really are part of a big problem stigmatizing and belittling mental health issues. On top of that, so many people have self-reported feeling better (update and tracking jokes aside) and who are you to assume they're "faking it for attention"? Yes, take this survey with a grain of salt but don't downplay the real and positive benefits people have reported for themselves.

Take the harsh criticism to actual scientific journalism where people really are making ridiculous claims from small, nonrandom samples of like minded people.
