Gender disappointment

Having a baby is a miracle. Its a blessing and ill love my child no matter what... I really got my hopes up for a boy.. And not really wanting a girl. I know girls are more harder to raise...Can someone tell me their experience about gender disappointment? I feel horrible for feeling this way and i know im not the only one :( is raising a girl not as hard as i think? Will i be a good mom even if im sad about the gender? Ill still love her.. Just doubting myself...
