every experience is unique. It's simply that, as a statistic, a non-nuclear home setup is one disproportionately rife with instability, chaos, and sometimes abuse. My single parent did the best for me, but it'd be hard to convince there's a "whole" home, when there were some days where I had to fend for myself with rice and beans a 12 years old, or when rent gets too high and we ended up rooming together with a 2nd single parent family just to stay afloat.
