living away from family with 9 month old and no. 2 on the way.

I'm sure many people can do it but I'm struggling now. Been 10 years on the other side of the world from my parents, siblings and family. Married to a man who comes from the same area as me. He says he hates it there but if we had to go back he would. I don't want him to go back if he hates it but I have had enough now. No friends even though I take my 9 month old to groups.As a teacher i work in so many different schools i can't make friends that way. Soon i go back to work thankfully. Sick of listening to crying all day and having nobody to visit or see other than my husband. Nearly 9 weeks pregnant. I don't know what to do. No friends or family is killing me. It's been 10 years. I want to go home :-( Now I want to go back myself and let him stay here but how can I do that with our son. It is so hard. I have never felt so upset:-( any advice.. what would you do
