history: I just moved to a new city for a new job and I've been so busy I haven't really been able to go out and meet new people.
current: I recently moved to a new city to start a new job. I've been so busy I haven't been able to make any new friends here and no one I know lives here either.
next: Ah, I know that feeling well. My family moved around a ton while I was in grade school, so I don't really have many long term friends. Don't worry though, you'll make friends at your new job so easily, you won't even remember you didn't have friends!
