How To Let Go!!!?

Well, I am a 23 year old whom is trying to conceive. My husband and I have been trying for over a year now and still nothing. I am a christian whom believes in God 110%, however it feels like I am at the end of this crossroad. All day every day I think about being pregnant, and it is taking a hold of my entire life!!!! PLEASE help me, I need to know just how to LET GO of this beast that is controling my WHOLE life. I need to face reality and know the worst, but hope for the best. We have not been tested or anything, however, after trying for soooo long I just know in my heart that I may live the rest of my life not being able to oneday have kids:( Please any and all comments are accepted!!!! Thank you in advance
