It eased off for me once I stopped mentally hedging on friendships and just committed to acting like I was staying indefinitely, regardless of what my actual plans were. The half-holding-back was the real problem, not the moving itself.
I'm more settled than a classic "nomad" at this point but the mindset lingers — I keep half-holding back from investing in local friendships because some part of me still feels temporary, even though I'm not really moving on any time soon. Anyone else caught in this in-between feeling?
