imo it's over if;
-if you're past the age of 18 yet you've never even properly interacted with someone from the opposite gender (assuming you're both non-relatives around the same age), let alone hold hands, hug or kiss each other.
-if your relatives feel the need to constantly gaslight your ass and tell you how good you look, yet you've never heard a single compliment from a chick your age
-if you get laughed at the tiniest mistakes you make
-if people never seem to take you seriously when compared to others (or at least if you heavily feel that they don't), even if you do something outstading
-if you get gaslighted with the classic ''everyone has different tastes'', ''pErSoNaLitY'', or ''i kNoW tHiS gUy'', and ofc people saying that you'll slay after HS/your 20s/college/whatever the fuck ends too
-if you had to constantly look for advice when it came to teen love or social interactions
-if you struggle way more than the average person when it comes to everything concerning social interactions (having friends, going to parties and stuff)
At least that's what I've experienced myself
