May I just feel sad and frustrated for a moment?

Don't get me wrong...I am SUPER excited for the other gals on the ttc forum who are getting their well-deserved BFP. My heart swells with joy for them. But it seems like it's been happening left and right this past week, which leaves me feeling so alone in my infertility journey. As many of you know, my husband and I are attempting another IVF cycle, but have had to resort to using donor eggs. Because our chosen (anonymous) egg donor is in college, we must wait until she is free from school in June to be able to fly into our state/city to begin the cycle. Each day feels like a month, each month feels like another year. And I feel so helpless, since I am not in control of how her stim med injections go, or things like that. I'm trying very hard to look at the positive side of this, as far as June is just around the corner...but I've been ttc for 15 YEARS. And if this doesn't work, it's the end of the line for me. Anyone out there please have some encouraging words for me? Or just send me happy vibes? I would really appreciate it. Infertility is so painful, and no one understands except gals like you who've been there too.
