If there's nothing you can do about it then why blow a fuse? Pretend you never said it or something. Freaking out about stuff like that wastes too much time and energy.
I'm not saying you shouldn't vent or anything. Venting is good. Venting is healthy. Just don't get too worked up over something you have no control over.
I told this girl i liked her tonight and she hooked up with my best firend. SHIT. And i cant do anything about it. FUCK. Me just venting
