A personality profile test on the grayshadow blog (http://shadow.sombragris.org/) produced an amazingly accurate profile:

Stability results were moderately high which suggests you are relaxed, calm, secure, and optimistic.

Orderliness results were low which suggests you are overly flexible, improvised, and fun seeking at the expense too often of reliability, work ethic, and long term accomplishment.

Extraversion results were moderately high which suggests you are, at times, overly talkative, outgoing, sociable and interacting at the expense of developing your own individual interests and internally based identity.

messy, disorganized, social, tough, outgoing, rarely worries, self revealing, open, risk taker, likes the unknown, likes large parties, makes friends easily, likes to stand out, likes to make fun of people, reckless, optimistic, positive, strong, does not like to be alone, ambivalent about chaos, abstract, impractical, not good at saving money, fearless, trusting, thrill seeker, not rule conscious, enjoys leadership, strange, loves food, abstract, rarely irritated, anti-authority, attracted to the counter culture

If you have the time give it a try. It might reassure you that you're not nuts after all!
