I don't know how old you are, but I think that what you describe was just the natural course of things before social media, and everyone got through life just fine. Yeah, you lose contact with your old friends, yeah you lose updates from close but not immediate family. But you also start your own family and become way more involved in them. That happened to my grand parents, my parents, and myself. I think the idea that you have to be up to date on everyone's business you've ever met seems to be a new phenomenon, and maybe the solution to all this is to just be comfortable with the idea you can maintain a relationship without being in constant contact. I see some of my friends once or twice a year. None of us are on Facebook or social media. But we have the same relationship dynamic we've had since middle school, despite differences in time and space.
