Why are your hours unsocial? What does your job involve and why do you not like it? What would you rather be working as? (sorry if I'm asking too many questions)
btw, not having a relationship won't have an effect on your employability. It's true that you may find life boring without someone to share it with but you'll learn how to deal with it. I was once so desperate that I went on an online dating site and got scammed, now it appears I am fine without friends and I think you will be fine too.
