I don’t disagree with you, total time waster. I believe it is mentally unhealthy, a few years back I lost it. This probably sounds really dumb but I was struggling, long story but someone I know posted a video of Aleppo, a hospital with a bunch of kids and music with words at the bottom, it said the children had survived a chlorine bomb in their village but not many survived. Then as it goes on the video shakes and powder filled the hospital. Nurses grabbed babies and held them to their chests as they screamed and cried. It was another chlorine bomb and I knew as I watched it they all died. I called my husband hysterically crying, I know it sounds stupid but I sobbed “how can people be so evil” and a bunch of other stuff. I calmed down but obviously freaked out my husband who was ready to come home and make sure I was ok. Then next day my sisters friend died of breast cancer and I was so stuck in this misery that I saw everyday with crime shows, friends/family posting about abortion and news and just depressing stuff and I thought “this is my life, I just get to watch people die forever” absolutely irrational but I couldn’t handle it. FB/social media is not what broke me but it definitely didn’t help. This was almost 5 years ago and I go in waves because you are correct, it sucks you in.
