How to get excited for fertile window?

I'm approaching my fertile window, and already I'm feeling like it's useless. It's only been 3 months TTC so far, and usually I'm excited and hopeful before my fertile window. This month, not so much. I'm already anticipating the emotions I'll get when AF comes. Last month was awful, being a week late but BFN. I just was so excited! I used to be excited about TTC. It's not so much fun anymore. The scheduled sex and peeing on opk's are grating on my nerves, the tww is torture, and I feel like my whole life is being consumed by the thing I can't even control. So - how do I get psyched and excited for my fertile window when I'm totally not feeling it this month??
