Install Skype on your computer and keep your Facebook updated

Set up Skype dates with your friends once in a while to get over the homesick. When you talk, talk about your new town and experiences not how much you wish you werent there. Sometimes we get hit with culture shock or loneliness and its understandable to feel overwhelmed. Remember you will be home eventually though and you have to make your own experience enjoyable. It doesn't automatically happen.
