There's a tendency to think social isolation is bad or think something is wrong with us for doing it. IMO most people who go out and party all the time are also just "socially isolating", by putting up a front, drinking etc, with no real deep connection. No vulnerability and openness. If you have deep relationship with family you are probably better off.
Your wisdom could be telling you not to waste your time going out with shallow folks. Having 1 or 2 deep friends is nice.
