Gender disappointment

Please tell me I'm not alone in this. We found out today that we're having a little girl. Obviously we love her but our hearts were set on a boy. We've just had this feeling that it was a boy. It's always been a boy in my dreams, we've always referred to it as he, we were just so sure. Buuuut we were wrong and now we're both so disappointed which makes us both feel like HORRIBLE parents. Idk it sounds dramatic but it kinda feels like we're grieving the loss of a son we never had. This is our first baby and we only ever planned on having one so our dream of having a little boy is gone forever. Idk. I feel like the absolute worst mother in the world because she's healthy and that's all that should matter. Please tell me I'm not the only one who's dealt with this :/
