Sometimes, when I feel sad about someone or I overthink, I just immediately think, "It doesn't matter." Not that the person I'm infatuated with doesn't matter or the thoughts don't matter; it's just me telling myself that what I feel doesn't matter and it's a great way of coping for myself.
Never said it was healthy but goddamn, it's so justified. It's a great way to just dismiss the matter because it really isn't important for anyone else other than me. So does it matter? No. It doesn't matter and I get to live with that.
It's my head singing "I'm done with you, I'm ignoring you. I don't wanna know."
