Not excited about this pregnancy?

I have always always always wanted a son since I can remember. The thought of ever having a daughter made my stomach sink to my feet. I was a tomboy growing up and have always bonded with boys so much better than females. I mean, I have female friends but for some reason I bond so much better with men. Anyways, I have a daughter now who will be two in July. When I first found out she was a girl, it was a slight let down but all in that same moment I was actually excited! My daughter is my world, I love her so much she is a mommas girl to the core and definitely caught my heart the moment I first payed eyes on her. I am now pregnant with #2....another girl. I have to say, saying I am disappointed is an understatement. I am very thankful that so far she seems to be healthy, and am ashamed of myself for feeling so hurt about her being a girl. But I can't help how I feel. When I first found out I fell into a deep depression. Didn't talk, hardly ate, just stayed to myself. In private, I cried about it several times. She will be here soon and although I am no longer in my depression, I still feel sad. I don't want anymore kids after this and neither does my husband. It's sad to think I will never have my son. Never buy boy clothes, never have my little man. Is this normal? How do I feel better about this? Any advice and experiences are welcome. For anyone who chooses to bash me (I'm sure a few will) I fully realize how lucky I am to be able to carry life and to have a healthy child, yet still this hurts me deeply. So I don't need any lectures, just understanding.
