Mixed emotions

So it’s official I’m having a boy. I’m okay with it but not excited. I was hoping for another girl but god had other plans. I love my daughter so much and I only have nieces so this is the first boy and I’m scared because loving girls is all I know I’m afraid I won’t have the same love for my son. I know it’s probably an irrational fear but I can’t get excited because of it. Has anyone else gone through this or have any advice to help. Please don’t be negative or rude I’m just looking for advice or words of encouragement.
