I'm honestly not too picky about my source unless it's a source I know little about and can't gauge their slant or bias, or if they're a known propaganda pusher or right wing fearmonger. Honestly though I've been trying to avoid following the news in general because it doesn't put me in a good state of mind, and usually if it's important enough to know about, I'll hear about it one way or another.
One bad habit I've been trying to kick every since leaving reddit though is trying not to read the comments of any given news article without reading the article, or verifying the known facts. A lot of times in the past, I would see a distressing headline, pick out details from the comments, and form an opinion based on the discourse which is not a healthy way to approach current events. Now if I'm going to get invested in a particular event or situation, It's going to be after I have a good grasp of the details free from influence from the comments on how I should feel about something.
One of my biggest pet peeves though is someone posting a paywalled article, and noone providing anyway to access the article. Too often that would be the article that would hit the front page, which made all the more clear to me that many people were doing the same unhealthy thing I was.
