I was in a similar situation to you when I moved to England. I never realised how much I would miss my family, especially my baby brother. It was really hardfor a while and when I go back for a visit and then leave it gets hard all over again.
You will miss them but as long as you hae some sort of contact it will get better. Talk on the phone as much as possible and on the internet. It will get easier. You may decide to go back to them, but you can't force yourself to make a decision. You haven't been there long by the sounds of it. You will soon adjust and then you won't feel as emotional and it will be easier for you to make a decision.

Hope you start feeling happier soon!
