Insult to injury

Just when I taught it couldn't get any worst.....My family is visiting and now they want me to go out with them, along with their children....on what you call..... a fun week.
Fun week- children games,foods,toys,outing events and a million and one...children festival.
Just when I started to feel better about myself and be happy.... with just living ....doing the things that I enjoy.
Here comes the family with their children....like as if i need to have a reminder that I am having issues with carrying a full term pregnancy.
I just don't why these things continue to happen to me....I don't want to weigh myself down with worrying,hoping and interacting with other people and their children.
To add insult to injury...my honey wants me and him along with his friend along with 4 children to go out and hang out.....like a fun day.
I don't have anything against people with children....but I am sick of them looking down on me.I don't have children....I want children...and I am having diffuculties.
I don't need a  reminder...that I have no children and that.... I am not like them.That I .....stand out ...anytime they start to talk about their children.
