Feeling spiteful :-(

Stacey
I hate feeling this way and I feel so awful but me and my fiancé have been trying for a baby and it's what we want more than anything in the world and today we found out his sister is pregnant and I just feel so spiteful and I can't be happy for her because I feel like I deserve it more, I know it's ridiculous but I just can't help the way I'm feeling! Please tell me I'm not the only one feeling like this!!
