Do you have tumblr saviour installed? Or Xkit? I blacklisted a bunch of tags I found depressing, and even without any serious triggers, blacklisting makes tumblring so much more pleasant. 🙂 Never be ashamed of taking care of yourself! 🙂
No shame in dodging things that batter you, nope! But mostly I’m good with scrolling on by things I don’t want to deal with. In this case it wouldn’t have helped anyway, as they were news items, and all three of them were of very different types (the SFWA sexism kerfluffle, NSA surveillance of citizens, and the latest women-stalking creepercam). They’re the sorts of things I WANT to know about, really; it’s just that the crapola isn’t usually that condensed.
Anyway, I have countered the mood by doing a bit of betaing and sharing some love for my fellow Tumblrites. ^_^
