I don’t know the details; but, I believe establishing ‘bi-polar’ status as a disability helps get your ticket punched for free housing and even tuition assistance...maybe through SSA.
Bipolar (formerly known as manic-depressive) is a real malady. It has nothing to do with multiple personalities.
Bi-polar is not the same thing as “Multiple Personality Disorder”. Bi-polar is what they used to call Manic Depression, it’s like drastic mood swings but no separate personas.
