I absolutely recognize how problematic and potentially dangerous such a test could be if it both existed and was offered in reality. HOWEVER, this is my greatest dream/fantasy as a questioning person, and I think I'd break down in literal tears of friggin joy if it were a thing.
Uncertainty is scary as ->-bleeped-<-, emotions freak me out, and introspection ain't my strongest suit. I want this decision out of my hands: objectively, quantifiably. Like, listen, I'm not the kind of person who likes to circle-jerk to the empirical, but if I could get a number scale on this? Yes, yes, yes! Give me something that said ''you weren't delusional and here is the proof'' because I'm gonna tell you right now that without it, I'll be spending the next 7-10 years talking myself in circles. I don't care about the subjectivity of human existence anymore. I don't want to hear how my feelings are my own, and only I can know what they're like. I mean, it's true, but jeez, send me a clear and tangible evaluation and I'll die a happy man.
I'm a medical student: blood tests I understand. But all this? Friggin BEYOND me. Hell, I'd take a Sorting Hat at this point. ''Welome to Hogwarts, you're a man/woman/non-binary person, as degreed by this magical talking hat!''
