Feeling down... just found out gender

And baby number 2 is another girl. I prayed for a son the first time around, and was saddened to find out she was a she. I've been in love with my daughter since day 1, but it truthfully took until seeing her for me to get over wishing she was a boy. Now the second time around you'd think I'd learn how much you love your child, not their gender, but I can't lie, I'm heartbroken. I feel at least with the first, I knew there'd be more chances. I not sure I'd consider a third, the thought of three girls scares me. So now I feel like I'm mourning the loss of the son I'll never have. I had many visions of life with a son. I can't stop crying. I don't even want to share the gender. We haven't shared the second pregnancy with anyone but immediate family, and now I don't want to. I feel horrendously guilty about all this. I'm personally the second daughter and wonder if my parents felt the same way about me. I think of the terrible relationship I have with my mother and realize she must have.  I feel so sad about everything... who I am, how my life is going. I know how I sound and am far too embarassed to share these feelings with anyone but perfect strangers.
