As an observer, the most alarming thing to me about this whole "raising awareness of mental illness" movement is that it's another judgment-forbidden sort of "every subjective experience is equal" movement. It's gone mainstream, too, in the usual sickening, missing-the-point way; you now have neurotypical college students with essentially easy lives drawing posters and holding fundraisers. It's not surprising people with authentic mental illnesses are rolling their eyes.
The downvotes this person is getting are a symptom of exactly this problem. "How can this person belittle someone else's illness?" In other words, everyone's illness is equally important. We've got to be diverse and inclusive. Never mind that some cases of mental illness are actually more severe than others. If everyone's entitled to their own perspective and experience, isn't this person entitled to theirs? Why downvote that? Because it doesn't fit into the modern mental-health-awareness agenda?
I think it's important that instead of lazily saying "everyone's suffering is a problem," we discern between degrees of suffering. Partly because perspective matters, but also because being told your problems are non-problems compared to someone else's is a helpful thing. The truth is, most people's problems are to some extent self-inflicted/self-created, and it's never a bad time to examine the size of that extent.
