When guys in middle school would get dared by their friends to ask you out and see if you say yes as a joke
How about growingupugly and then turning out sort of okay looking but you don’t know for sure because your self esteem is shot and you’re convinced you look awful?
Being so wholly convinced of your hideousness that as an adult you now literally cannot even imagine that someone would pay you a compliment and mean it; the only conceivable thing that could be happening is that they’re either a) taking the piss like the boys in school used to or b) so repulsed by you that they feel sorry for you and are telling you you’re pretty because they think you need to hear it.
Being saturated in messages telling you that you’re less than unworthy. Being convinced for a majority of your life that nobody will love you. And not being aware of it until someone does love you, genuinely and completely. And it turns your entire world sideways so harshly that you have a total mental breakdown over it.
