Dear Michael,
Thank you for your letter. I was surprised to read that you feel so sad in London. I know that you are now in completely new place, but it does not mean that you have to be lonely. You can do many things to find new friends in your neighborhood.
First of all, you cannot stay at home all days. You have to go out, walk in the city, visit some club or pub. There are certainly many people there and you could easily meet them there. Go out, go to the park, try to talk to people you meet. Did you get to know your neighbors? If not, do that. Go to them, introduce yourself, ask someone to visit you.
I believe it is really difficult situation. I understand, how you feel. But you cannot say that there is nothing to do to change that and that it will be like that forever. Follow my advices, make an effort and you will see that this may help.
I wish you all the best
Ahahaha
