Whats wrong with me? (i can just sit there and think ALL DAY LOnG)!?

I dont drink. i dont take drugs. i have a bachelors degree, but not a job yet. i'm currently living at home at age 23. no boyfriend. one younger sibling. AND I can spend an entire day just sitting there and thinking. i just waste my days away being unproductive. HELP, what should i do?? i dont have much energy and i'll sleep or day dream or think. i'm a dreamer...how do i turn myself into a DOer??
