You should watch your words carefully today. Your temper could be running hotter than you realize, and you don't want to burn any bridges. Try to keep things impersonal and bite your tongue if you feel yourself getting upset. It's not that your emotions aren't valid. It's just that the people you'll be around today either aren't going to want to hear it, or they aren't going to be able to help make you feel better. By being stoic, you'll be taken more seriously.
