Why are you worrying? Why are you overthinking? Some “chemical imbalance” in your brain? No. Don’t blame this on science. Blame this on you. Blame this on yourself letting you worry. On letting yourself overthink. Be sad if you want. Be down if you want to. Sure, go ahead and let yourself feel shitty. But while you let your heart sink down to depths you wish it wouldn’t go, you so easily have the power to pull it back up. You so easily have the power to be happy. You can be happy. You don’t have to worry right now. But you’re wasting all of your energy on the useless overanalyzing.
Why? Stop. This is pointless.
