Anyone else scared to find out their baby’s sex?

I’m not sure I can handle finding out the sex of the baby. I know everyone says as long as it’s healthy, but I don’t feel so unbiased. I’ve just always pictured myself with a girl and I would totally love a son, but I would be somewhat disappointed at first. I’m not sure I can handle it right now. I think what’s making it worse is that my in-laws want a boy. And my sister-in-law asked me what I wanted, so I told her I was hoping for a girl. She flat out tells me girls are awful and she hopes I get a boy. How shitty right? Why does she care? We aren’t close, her kids are already 10+. It just really pushed me over the edge. Why ask and then tell me you hope I don’t get what I want? I’ll be ok if it’s a boy. But it might take some time, and shitty family like that sure doesn’t help. I’m just thinking maybe it would be better not to find out before birth. Is anyone else feeling apprehensive?
