How do you keep your self positive?

Gosh ttc is so freaking frustrating. Im so down and depressed today. I thought this was our month for sure i guess not :( got a bfn this morning. What do yall do to keep yourselves motivated to keep going? My hubs and i havve been married 9 years now together 13 and have honestly never done anything to prevent pregnancy. I have pretty much come to the conclusion its never going to happen for us.
