It's probably a conbination of so many things Yvonne...
You wanted to get pregnant and went through all the stress of ttc and then you finally get pregnant and it's probably anti-climatic because you don't really have anything to show for it yet.
It just more worries.
Then you've moved to a completely different country where you know no one except for your husband and he doesn't seem to appreciate how lonely and vulnerable you are feeling.
You want to feel that comfort that you can only feel from familiarity.
Maybe it was all supposed to be a fresh start and the reality of the situation is that nothing has changed except your geographical location and that you lost close contact with your family...
It might not seem it now, but it will get better in time.
Don't put pressure on your husband to fill the roles of all your family that you have left behind, because he can't on his own.
You need to make friends. Good friends. That can only be done in time.
Involve yourself socially at work, at your daughters school and volunteer locally in something you are interested in. Get a rountine going and you'll soon notice the same faces and evertually become friends
