Faint Hearted - How do you stay positive?

I have had issues with my cycles since a year after they began. I was diagnosed with PCOS a few years ago. Now my husband and I are TTC. It just feels so disheartening sometimes because our friends are having children, and he has a child from a previous relationship. We both knew going into this that it could be a challenge. And with some help I have been having more regular cycles. How do you gals keep your chins up while TTC? What encourages you?

Thanks !
