I mentioned "non-creepy, non-prying" because I've been on the internet a lot and understand internet culture. Several things mentioned in your post give a distinct vibe of the type of person whose brain has been so overcooked by the internet that they have a tendency towards being creepy. I'm specifically talking about stuff like:
feel like liking someone is a need like taking a shit. if i give too much affection, would a girl get scared and run away, or fall in love with me? what do i do if i accidentally make a girl love me?
i don’t want girls to love me too much. how do i make them not love me too much and still be myself?
what do i do with the freedom and power to do whatever i want?
I am not autistic, mentally ill, ugly, or weird (I guess those last two are subjective). I have no diagnoses at all and have never been regularly medicated. I am happily married (June will be my 10 year anniversary), with 2 kids. I also had previous relationships before meeting my (now) wife, so clearly I'm not so hideously unattractive or weird as to repel everyone.

Yes, it seems to be a real word in Ancient Greek, although it didn't seem to have any special significance beyond it's definition.
