It's wrong I know...

I just found out I am having a boy yesterday. My husband and I were so sure it was a girl because my pregnancy was so different than with my sons pregnancy. I know it's wrong but I cried and was dissapointed. My best friend has infertility issues and I feel so stupid and ungrateful for feeling this way. Ive also been going through this pregnancy depression which is also unlike me because I usually have self control and I am very headstrong...*sigh...any other mommies feeling a little blue? Please tell me It will be better, my husband is also going through depression due to family problems with his mom and siblings so I dont want to burden him with my feelings.
