From ok to bad to worse

So I was feeling ok a little while ago and then my wonderful DH needed to go for a walk..so I went with him...after all loosing 30lb does require some exerice. On our way we saw one of our friends who told us that they are now expecting another child. THough it is wonderful news it did make me feel bad...then I dwelt on it and now I feel worse. I am beginning to feel like I do nto want to hang out with my friends who have kids. It is not their falt I feel this way, I just can not handle it right now. I am still guessing that it is the hormones talking instead of me really feeling this way...So I am feeling bad and depressed again...I just a break and a pick me up.
