To clarify: Is it that your folks are pushing too much of a kind of socialization/affection that's a poor fit for your emotional needs? That once you're home, the net amount of affection available to you is insufficient? That you run different social "programs" based on who you're with, and shutting down the one used with your blood-family is a long & resource-intensive process? Or something else entirely?

Anyhow, it's not just you. When I visit my relatives, I need a substantial amount of recovery time afterwards.
