idk why but i feel like crying

everything's going pretty good in my life for the most part and i really don't have anything to be upset about but i'm just so fucking frustrated for some reason and it's killing me. i feel like i deserve something more out of my existence and like i'm grasping for something that is on the tip of my tongue but for once, i find it hard to verbalize. i just want to sit down and have a good cry but i'm at school and i have shit to do so i really can't. just waiting for the day i can feel happy and satisfied without any strings attached. i want things to feel just perfectly right.
