Help ladies!! I'm obsessed with TTC😣

Hi ladies, I'm 39 and we've been TTC #1 for almost a year now, My DH is great, but he even tells me to stop obsessing about having a baby.  I feel like my whole life (and future) is planned/on hold because of TTC.  We have a room which "might" be a nursery.  We can't plan next Summer's trip to Europe because I "might" be pregnant by then, everything is "might"😒And the 2WW kills me everytime - I'm completely useless - wondering at every twinge, are my boobs sore, am I unusually tired, am I nauseous, the list goes on. In some ways, knowing now that I'd never have kids would mean that I could at least make the best of the life I have now, without all the wondering.  What makes this harder is that I'm healthy, the world's most regular periods with a good strong 15 day LP and gorgeous temp charts. My hormone levels are all good and the OPKs show that I actually am ovulating every month. DH checks out good too, I know I NEED to stop obsessing, but I can't help it😔 Help!!!
