I'm becoming bitter because I can't have a baby

I've never been a jealous person, but up until now I have turned into a seething, jealous, bitter hag. My husband and I hit the one year mark of trying to conceive this week. It is so hard. We have both undergone initial tests (all fine, except a few minor issues that doctors aren't too worried about) and have been referred for more complex testing. I am devastated that it has come to this.
