Well, I fail to see why you're reading or contributing, on the basis everyone is just a potential liar?
As it happens, my life is not that sad that I'd sit on a forum making shit up about such an important issue.
The "I dreamed of" posts I don't identify with as such. To me, they are one of two things. 1) A dream, just like they say. Then the fantasy is smashed and they feel the sadness. The perfect life they had created in their mind isn't going to play out and it's down to a 50/50 choice that was out of their control. These are nearly always the posts that are followed up with, the moment I saw DC, everything changed, I loved my child instantly.
Is that a really mild and temporary form of gender disappointment? Could be. There are different severities.
Or 2) That's all they dare admit too. A sugar coated version just to get something out. And inside they are crying for help but are too petrified to let anyone know. You only have to look at the comments on this thread to see why.
I applaud you for researching. And yes, there is still very little online resource. There's more now. Ten years ago when this happened to me, an online search solely led me to forums where people suffering the same were called freaks. That they deserved their child being taken in to care where it wouldn't have to live with such a monster.
Because of that, I stayed silent for four years until I met the most incredible doctor out one night, ended up breaking down in front of him, and he changed our lives.
