Gender disappointment

First off i am so eternally grateful that this one is healthy and low risk. That is the number one thing and the most important. I however am a bit sad that they told me i was having my sixth boy. My daughter has wanted a sister since she was old enough to know the difference and talk about it. I wanted her to have a sister so bad. I am a little sad because i also would have loved to have another little girl. Im not here to whine about it but i just can't say this out loud i don't want to be that horrible ungrateful person. I should be happy I'm so blessed. There are so many who would give their arms and legs for what i have. My heart just hurts a little. Im pretty sure this is going to be our last and i kind of feel sad i didn't get a girl. I should just be happy i have the one i have. Im sorry I'm rambling. If you've made it this far thanks i just had to let it go somewhere. I don't want me kids to hear me say that and think i don't want the baby because it's a boy because that isn't the case.
