Gender Disappointment

Has anyone experienced extreme gender disappointment? We found out the sex this morning and I cried and couldn't stop. I can't even think of it without feeling a sinking feeling and so much disappoiment. I put away every baby thing we had out and threw away our registry lists. I'm just so angry. My husband is zero help because he's perfect and of course didn't care one way or another but isn't saying anything.
I feel like a terrible person for being so disappointed. We tried for this baby for over a year and had multiple miscarriages and here I am acting ungrateful and mad at the world. I have read a lot today, through tears, that once that baby is placed in your arms it all goes away but how do I get through the next 22 weeks. I knew because I wanted something it would end up being the exact opposite. Karma I guess. 
I'm just venting because I'm hurting and hate myself for it. I want to call off the reveal and the shower at this point. I just don't care. Sleep is all I want.
