Oh hon, you are not a bad person for feeling like this and I really have every sympathy with you. Have you thought about counselling? I am defo going to start sessions if i get preggo again as i dont want to go through the pain of how i felt last time.
I know a girl who desperately wanted a little boy and couldn't understand the want for girls-I am pleased for her she got her boy but the anxiety she went through was awful and she did say she felt so shut out as no woman could understand her wish for a boy not a girl.
I can quite safely say if I already had a girl I would be trying for a boy and would be disappointed witha second girl-I understand the love and wish for boys and can totally see why some woman want them so desperately.
I am so sure that when your lovely baby comes into this world you will love her with all your heart. Until then be honest with how you feel, explore your feelings no matter how wrong they feel to you...Your not alone, all my love, Hope you feel better soon xxx
