All the way upto the shrink's couch

Brown and lyrical, thats me
Hairy and hysterical, also me
Illogical, yet infallible, yup, me again
Hopeful pessimist, no points for guessing who that is.
Amoral and righteous, again points to self
Irreligious and superstitious, look no futher.
What a mess of the contrary!
