Once I limited my time on FB I felt better, it is really affecting your mental state. Unfortunately I have friends that I will forever lost contact with so I can't delete my profile. I deleted the app from my phone and logged out from everywhere except from 1 pc that I usually don't use. Now I am going on FB at most once a week for 10 mins. It has improved my life a lot.
Tip to surviving Facebook: If you must go through your feed, immediately start "hiding" toxic/hateful individuals that post nothing but bad content. If an individual only sometimes does so, start hiding their sources. E.g. If you see some friend that happens to post bad stuff from CNN or Breitbart and the content from that source upsets you but you want to see that friend's other content, then hide the page they're "sharing" from.
Most of the time, people don't post original links/content, so it's a "share" from an existing page that you can hide.
That shit is basically guaranteed to make you feel worse about yourself. <3
Take care of yourself so you can take care of your kids!
