Staying optimistic and patient.

Okay, so my best friend just announced that she is expecting her third child. My husband and I have been TTC for 5 months, which doesn't seem very long, but feels like an eternity. I'm only 20, so I'm still a little impatient. He's also Army National Guard, and is supposed to be deploying to Afghanistan in May. Everything just seems so pressured. Its hard not to lose faith. Does anyone have any tips on staying optimistic and never letting your emotions get the better of you?
