Social media has become so terrible in the last few years that I've grown to depend on it less without even making an effort to. I deleted my accounts on the worst sites and only visit anonymously, which has trailed off over time. I've joined newer/better sites but haven't let myself get attached to them. If they go away it won't feel like a big loss.
In that respect, the worsening of social media has been a gift. I'm still online but with the attitude of: "Don't ever let yourself get attached to anything you are not willing to walk out on in 30 seconds flat if you feel the heat around the corner."
