Even if you do stay single your whole life, you definitely don't have to be lonely. Surround yourself with your family, friends, work, or hobbies. As a single myself, I know that sometimes these things don't seem enough. Use this time to make yourself the best person you can be, so that when your mate comes along they will fall head over heals in love with the person you are. There is a certain confidence and maturity that comes with finding out your own identity and not having to question it.
Singleness is a great teacher, so take advantage of it.
If you're anything like me, your tongue seems tied, you turn ten shades of red when trying to answer their questions. You don't know the answer to their questions any better than they do. All you feel now is embarrassed and like some big loser because you're not in a car pool or knee high in diapers. Being single can be tough. Watching happy and unhappy couples can be very educational and exciting.
