Day 3 First Appointment after 3 years of infertility

Tomorrow is my first Day 3 appointment.  We will also be receiving all of our test results (both my husband and myself had our blood tests done and my husbands semen analysis).  This is our first month with a reproductive specialist and I'm just so anxious and depressed some days that I can't get out of bed.  Other days I feel like I just climbed Everest!  I know this is just the beginning of a long journey but I feel like I have no control.  Anyone else out there that can help give me piece of mind?
