Something similar has been happening to me over the years, although I try to stay connected with family and some friends so that I don't become strictly isolated from myself, because it's not very healthy.
So your decision to re-establish connections is extremely healthy and beneficial for everyone, but mainly for yourself, for all of us who are at the same point.
YEah, I basically isolated myself away from everybody except a couple of people outside my wife and sons. It feels good to start reaching out and establishing those connections again.
