Current events in generally are frequently extremely depressing and sometimes even give me anxiety attacks. I try to avoid reddit in general when I'm feeling broken, but stuff like r/wholesomemes are usually okay. goodnewsnetwork.org and positive.news are both great. Buzzfeed would be passable but I have a strong aversion for astrology and celebrity gossip, not to mention they have a news article on their front page most of the time. Popsugar and Mentalfloss are usually pretty good.
