2. Don't Obsess over Worst-case Scenarios
Maybe your crush won't decide to come until the last possible minute. Maybe he or she is bringing a date. Oh god. Who is it? Maybe you should bring someone too, just to be spiteful – wait, no, just to make your crush jealous – wait, wait, no! Stop. Nope. Remember, you can't control what anyone else does so just hope for the best and prepare to have fun because um, hi, it's a Halloween party!
