The last line you wrote was brilliant, "I have to come to a reason why this means so much to me, why do I desperately want a ___".
This question must be answered by every parent (mom and dad) who truly feels that having their DG is a must not a want. In real life, all the women I know that were freaking themsleves out over having a girl all had mother issues; either they had a broken relationship with their moms OR they had an unusually close relationship with their moms. The broken ones felt wounded and if they could only have their own daughter then it would fill their perceived hole in thier heart....boy, did that work out real great with one woman - her daughter is the complete opposite of her the moment she turned 13 she began pulling away, she's now 19 and is such a strong and confident young woman that she RESENTS how needy her mom was/is and doens't want to be close to her. How IRONIC...the girl was born to fill an emptiness but only led to more pain for the mom. This is because we, the grown- ups, are meant to shape, mold, and STRENGTHEN the child....not the other way around.
Maybe you think your husband feels the need for a boy and you're disappointing him? I think that tends to be the reason for many. Or maybe you're just like me and get filled with passion and excitement for all things new and having a gender you never had before is soooo NEW! I really really want a girl, this is my 4th and final...but if I "needed" a girl, I would do some serious introspection - maybe begin a journal and unload all my deepest most private feelings- maybe speak with a professional who can dig deeper than one is willing to go on their own.
We need air, shelter, nutrition, and just as important we need a happy family and a peaceful home. This is what is owed to the children we all bring into the world.
No matter what happens, just imagine all your daughters giving you and your husband grandsons one day! Have you ever seen a more beautiful and tender relationship than a grandfather with his grandsons?? Especially if he had only daughters then it becomes out of control joy xoxoxox
