How to stop TTC?

We are in month 14 of trying. The first 6 months I didn't ovulate and then got on meds. After 3 more month of trying with no luck we found out I had appendicitis. I had emergency surgery and have ovulated on my own since.

My husband did the YO at home sperm test last night and it said he has less than 6 million count with low mobility. All this time trying, crying and hoping is wasted. Our odds are slim to none.

How do I get this out of my head? My whole life I have dreamed of a big family and now we will be lucky to get just one.
