Found out genders today

I can't believe I am even saying this, but I found out today we are expecting identical boys and I am so disappointed. We have an almost 5 year old son also. I am so thankful the babies are very healthy and growing well, but I just can't shake this feeling of disappointment that I'm just never going to get my girl. Has anyone else dealt with gender disappointment?
UPDATE: Day 2 and I'm still a mess. I get myself together for awhile and then all of a sudden I'm bawling uncontrollably. I know people don't realize it, but saying 'you'll have to try again for a girl' is really not helpful! I am thankful that I'm not alone in this feeling and that it seems to go away at some point.
