The world is doing very well in breaking down some of those stigmas, especially mental health; having major depression and/or anxiety is no longer "frowned upon" (at least not from my perspective and experience).
Somewhere I read a study that even social media itself contributes to depression. Probably more people suffer from depression than we think.
However, the ones like "Addict", "Alcoholic", "Anorexic", "Suicide Survivor" etc., while requiring the greatest amount of balls to claim (which is often the first step in healthy recovery), are the ones that are most judged.
It may be hard, but I know people, who show online, even on YouTube videos that they are addicted and/or alcoholic.
And it's the judgement that most people avoid, hence online anonymity.
Even with all the judgement one may receive, it is still worth it to admit these things, and seek help (professional, if needed). It helps to start taking steps towards recovery, like you said.
