Your mother calls you in the morning one day, and informs you that she doesn't have to work on Friday, and asks if you're free that day. You look at your calendar, and shockingly you have neither work or class. "Perfect!" she says. You're excited to see her since you had to cancel on her birthday dinner, and you can still give her her present now.
Your boss calls you to talk about whatever it is that she warned you about. Preparing for the worst , you're slightly shocked. "Hey, I really need you to show up to work a little more. I know you have a lot going on with school, but we really need to see you because you do a good job. Because of that, we will consider giving you a raise soon, but only if you prove you are reliable." You can do that for sure. You're excited to continue your job and double excited at the prospect of a raise.
It seems that your fears are just those. Whatever scenarios you've created in your head are not reality, and the people in your life care about you enough to see past whatever transgressions you feel you've made. You realize that everything turned out fine in the end.
End. Try again.
