Feeling a little sad, wanting to give up

Today is one of those days where I'm feeling really sad and want to give up on thinking about trying to get pregnant. Ive been in my fertile days since wednesday and wednesday morning was the only time I BD. My OH hasnt been feeling good and has been really tired so I know I'm gonna be out this month. Really think I'm going to stop tracking for a month and see what happens. All of my friends are pregnant and keep asking if ill be next. Little do most of them know ive been trying for a year with no luck while they're lucky enough for it to "just happen on accident". Being around all these little babies though has reslly been pulling on my heart strings. I want it to happen but im so tired trying and tracking. :( any words of advice?
