How do you deal with the disappointment of AF?

I don't know how to not be upset about the arrival of AF today. I'm so sad and disappointed that I couldnt make it work... again. Honestly not sure I want to keep trying. I didnt know I wanted it this bad till I thought I could have been pregnant this time- weird symptoms and not the normal lead up to AF's arrival.

I could use some positive ways to cope...

Thanks in advance...
