Acknowledge your sense of failure
Maybe not a lot and maybe not for very long, but you most certainly will feel like garbage. No matter how the world sees or treats me, I basically feel like I've regressed out of adulthood. And that messes with me. But instead of hiding that, I'm learning to accept those waves of self-loathing and am trying instead to use that fuel as inspiration to get my shit together.
Know that fights with your parents are going to happen
My mom and dad still think of me as a kid, just like yours do. They’re not particularly overbearing in general, but once I was under their roof again (which they've reminded me of, many, many times) things got messy.
There is no worse feeling than being a grown-ass adult whose mother yells at you to clean your goddamned room, or because you stayed out too late. They’ll get on you about big things, too: pressuring you to go back to school, get a better job, find yourself a serious relationship, and get some direction in life.
