Feeling down tonight

A little background...My husband and I have been trying to concieve for over 2.5 years and nothing. We both have grown children from previous marriages, but I have always wanted another one. (Im 38). Well tonight it has hit me hard. Seeing all of my friends children in their Halloween costumes trick or treating and I dont have a little one to do that with. Hell my dog wouldn't even let me put his costume on him! Idk why, but I cried. I came into the bedroom and cried. I guess I just needed to release those feelings for once. I'm sorry for venting and spoiling the mood and fun time of Halloween. I hope everyone had a fun night. Thanks for listening.
