"Sacred Rituals". This is what I call things that have to be done exactly the same way every time or it screws everything else up.
For example, as soon as I get up, the very first thing I do is take my meds. Nothing, and I mean nothing, happens before taking my meds. Gotta pee? Can't. Gotta take my meds. House is on fire? That sucks. Gotta take my meds.
If I don't, I will definitely forget to take them and fuck up my entire day.
