I know how draining it can be to constantly having to talk to ppl and basically saying the same thing over and over again.
Can't you, like, maybe arrange some kind of schedule for updates or something like that? Like, you'll call person XY every day, and they will in turn call others?
Force the people around you to respect your need for solitude, dear. It is imperative that you have time for yourselve to refill your energy. As difficult as it may seem to tell friends and relatives to stay away, trust me, they will understand. And those who don't aren't worth any thoughts you give them, anyway.
