Discouraged. Anybody have an uplifting story

We have been TTC for 20 months. Went to repo endro November 2013 I wasn't ovulating. Did lots of testing. Started first round of femera this month. I ovulated successfully on cd 11. It is now cd 28 and 17 dpo and I tested. BFN again. Just feeling really discouraged. I work for an insurance company and daily I either have a call from someone who is prego just had a baby or wants an elective abortion. It's painful. Just needing some encouragement
