Does anyone else never know what they want to do and are just generally lost?

Ever since leaving school(which was a major shock) i've just drifted through life never knowing what i should do and always looking at other people wanting to be their lives. I get in such a muddle i just end up not being able to work at anything. I look am pretty sure all my old school mates will be working away and getting on with their lives but years on i'm still just drifting away. I just don't see the point in anything. I can't understand how others have all found a path and i haven't . Bizarre.
