An introvert:
Like biologist studying a colony under a microscope, he minutely examines his every thought, feeling, and action. Probing, futile questions like "What do other people think of me," and "How do I look," and "What do other people say about me," and "Maybe I should not have said that," are his constant nagging companions, for he is unable to realize that other people do not spend so much time and energy analyzing others as he thinks. He may seem unsocial, yet his greatest desire is to be liked and accepted. He may be shy and quiet, he is often moody and unhappy, he prefers the solitude or at most the company of one special person to a crowd. He has an aptitude for creative work and is uncomfortable engaging in activities that require cooperation with other people. He may even be a genius, or eventually turn into one.

Misanthrope: Cynical, embittered, suspicious, he hates everyone. The perfectibility of the human race? "Oh brother, don't get me on that topic." The stupidity, the meanness, and the crookedness of most mortals (most? More like all!)- that is his favorite theme

Ascetic: Self-denial, austerity, hunger, lonely contemplation, these are the characteristics of the good life, so he claims. The simplest food, if any, and the least amount of it that will keep the body and soul together, combined with an abstinence from indulgence of any kind of earthly pleasures, will eventually lead to the spiritual and intellectual perfection which is man's ultimate goal-that is his philosophy

Now do these not sound exactly like me?
