Not all relationships have to be romantic. Not all social interaction needs to result in complicating your life.
Find people who can provide those social "strokes" we need for our emotional health, our esteem. Friends, acquaintances, classmates--that interaction can fill the void to some extent. Stop thinking the only plug for the hole is love.
And it sounds clichéd, but learn to love yourself. That can go a long way in shrinking that void you speak of.
