Try not to stress out. You will get through the day. Things will work out. Life is a bumpy road. We should try not to plan for things to be smooth. Plans fall through. Things may not always go your way. It is a bummer and downer, but it is part of life. Remind yourself when things don’t work out like you planned. That things like this happen in life, and you will figure things out.
