as others have said dont be too hard on yourself, its a massive step moving away from what you know, being ill as well can all have an effect on your mental wellbeing.
Is there a local mother and baby club you could pop along too? Even a wee trip to the shops once a week to treat yourself. I moved to Scotland 4 years ago and didnt know anyone, it took a lot of pushing myself to get our there and meet people (i'd make all sorts of excuses not too) but now i love it up here, have plenty of friends and my DH feels happier for it too!
Could DH stop in one night so that you could attend an evening class in something that really interests you?
