To be fair, I don't see that line being crossed in tumblr user yipyapfox's little lament. In general, the idea of "person X is talking about their experiences more times than I find acceptable/in a way I, who am not person X, don't find acceptable, therefore they're making THEIR ENTIRE LIVES about it and they need mental help, I, the person who am not person X, know this because I'm a certified Internet mind reader"* quite aggravating tbh. It's "if you talk about your mental illness without hating yourself, you're romanticizing mental illness" all over again.
(not necessarily trying to put that in your mouth, it's the general attitude that your post reminded me of)
