NixOS ruined all other distros for me

Ever since I started to use and appreciate having a system which can almost entirely be described by a handful of text files it feels absolutely overwhelming to try to use a different distro. I still have an Ubuntu server for a few different services and I haven't touched it in ages because what used to feel like a relatively stable and simple setup I now see for the house of cards that it is. If any part of that system went missing or broke it would take me a not insignificant amount of time to remember all of the specific things I had set up and it's kind of weird how scary that is to me. I simply do not feel in control anymore because I rely so heavily on being able to trust what's in my config. Maybe I need to take a break and lay in a big open field or something but I manage so many different servers and computers that I just can't fathom not having the security of a centralised configuration. Is this common or am I crazy
