Hi Sammiez - really glad to know that you're feeling a bit more positive today. :) I think you've had some great advice from people, and I totally agree with ZZZenAgain that it sounds like you're actually doing a fantastic job already. I hope that the meeting with the teacher goes well tomorrow - do come back and let us know how you get on.
You mentioned some of the books that you have been reading to your dd, and you said that she hadn't really enjoyed them that much. I have tried both Enid Blyton/Roald Dahl with dd because I loved these writers as a kid. However, she hasn't really been that interested in either of them.:( She did like Charlie and Lola for a long time, but seems to think it's a bit "babyish" now. What she has really enjoyed recently are the Pippi Longstocking stories and the Worst Witch series - perhaps they could be worht a try for your dd! 
As for magazines, I guess it's worth trying anything that captures her interest - take her to the supermarket and see if she likes the look of any of them. Likewise with books from the library. The reading scheme books which children get from school are deadly boring in my view - enough to put anyone off reading for life. :( Perhaps she might be more interested if she could choose books from the library - but again, don't go into overkill if she isn't interested.
Honestly speaking, though, Sammiez, I am more worried about you than I am about your dd - from all that you have said, it sounds like she is doing really well, and that's not surprising because she clearly has an absolutely fabulous mummy who will do whatever it takes to give her a good start in life! But you sound so lonely and unhappy. :( It doesn't have to be that way, and I really agree with the poster who said that you need to do something to look after yourself. Raising kids is hard, and you have to reach inside yourself for all sorts of reserves that you never knew existed, but you also need a decent support network around you as well. I have really felt this myself, as we moved across the country last year for my job, and for the first few months, I desperately missed the support that I had grown used to having around me. And when you're struggling to do all that in a foreign country, it must be so much harder to cope.
I do so hope that you can somehow find a way to get out and meet people - maybe a book group or evening class, as someone else suggested? Or maybe the PTA at your dd's school? Or maybe just invite some of your dd's friends around to play and try to get to know the mums a bit more. The mums of children in my dd's class meet up for a meal one evening a month, and we all really enjoy it - it started off very informally with one of the mums trying to organise a get-together before Christmas, and it just sort of grew from there. Could you perhaps club together with one of the other parents to organise something like this? You might find that many of the other mums really welcome the initiative.
It may feel like you have been here a lifetime, but a year is still very early days and it's quite normal to feel like a fish out of water at this stage - have you read much about culture shock and how it can affect people? I lived abroad for eight years, and I think it took a good two or three years in the new country before I really started to feel more comfortable about stuff. I think the important thing to keep in mind is that it will get better with time - this country may never feel quite like home, but you will get more used to life in the UK, and you will start feeling more normal eventually. I don't know if it's any comfort, but my OH was really depressed in his first year here, and I really thought we'd made a huge mistake in coming back. He still dislikes some things about Britain, and probably always will, but he is so much more settled now - he has managed to build a life here for himself. :)
Which part of the UK are you in, Sammiez? (Quite understand if you prefer not to say :) )
