means To make or become smaller — and, informally, a casual (once mildly derisive) term for a psychiatrist or therapist.

from From Old English 'scrincan,' meaning to shrivel or contract, related to other Germanic words for wrinkling and curling up. The psychiatrist sense is 20th-century American slang, short for 'headshrinker' — a jokey, slightly irreverent nod to shrunken-head-taking tribal practices, applied to doctors who, as the joke went, got inside your head and (figuratively) shrank it down to size.
