Hi.
I feel for you too. We will have been living here 2 years in December and I have really struggled leaving family behind. I had a baby back in March and my sister also had a baby in April (she's in the UK, we were from Manchester too) I have found it extremely difficult without family support and seeing how much support my sister has around her. I have made some really great friends but still find it so hard without my family. I know it is probably going to be a much better life for my kids if I can ride it out but some days I just feel so down I just want to return to the UK. It's such a tough decision and I just feel so torn with it. I do use Skype regularly which does help, just have to watch the time difference.
Good luck with your decision.
