Well i don't mean to sound so 'morbid'... but would you, and your baby, be better off close to your parents and your friends.
It is going to be emotionally unhealthy if you feel isolated and depressed because the people you want near you are so far away. Of course it will be very hard without your DP, if he chose not to follow but surely if he has experience he can get work somewhere else? That and sometimes he will have to make sacrifices too?
