Our minds are beautiful. Able to help overcome pain, see past malice, protect us from the truth, create delusions so we don't have to deal with the reality. The mind's ability to create barriers and limits isn't a focused laser beam only taking away the bad and leaving the good, its often more like a clumsy grenade, leaving craters of casualties in the wake of destruction. Anything and everything can be controlled and limited in the powerful grips the mind has over you. Even love. "We accept the love we think we deserve." Because that's adapting. But it still hurt. Because it actually hurts more to expect anything else. But it still hurt. Because disappointment was norm. But it still hurt. Because anticipating being let down seemed better. But it still hurt. Because then it didn't scar all the way to the core. But it still hurt. Because life hurts.
Quote in line 13 from "Perks of Being a Wallflower" I believe.
