gender disappointment

Today, at our our gender reveal, my husband and I found out we are having a baby boy! I am really excited.. but I can't help but feel like gender disappointment. I had dreamed and hoped for a girl so bad. I fell in love with this beautiful girl name, pinned so many cute girly things on my Pinterest board, and even thought my gut feeling was a girl. I'm really excited and I know I will love my baby boy so much, but I just can't help but feel a little bit sad.. 😞is this normal? What can I do to be a little more excited for a boy and quit thinking about all those girly things I had dreamt about? I feel a tad guilty.
