How to stop thinking about TTC?

So I’ve been TTC since December 2017. I got married a month before that. We both want babies so much me especially . I’ve always wanted to be a mama. But it’s so hard. Every month I get AF and it makes me so sad. We are both perfectly fine but it’s still so hard . How can I get myself to stop thinking about TTC every time a new cycle starts I start obsessing over it all over again. I don’t want to lose hope but I wish I could relax and maybe it might happen somehow . I never ever imagined it to be so hard. Everyone around keeps asking when we will give news and as much as I want to I can’t. I just feel sad 😔
