Oh, that's nothing. There is no force on earth that can prepare you for being a homeowner after a lifetime of renting. Anything you would have called the landlord or super for, now you have to deal with, and you are liable for. That's not even considering the nervewracking stress that goes along with a mortgage, which payments you miss at your peril, and which refinancing is a nightmare even when it's favorable for you (and with Trump's economy, ironically, refinancing has been pretty sweet lately). There's a reason "mortgage" is based on the French word for "death-pledge."
The fun is just starting. Wait until the first time a pipe bursts, or the hot water heater goes, or something gets fucked with the wiring. A whole delightful new chapter of Wu antics is about to begin.
