When did “crazy” become “sick”?

Was it around the 80’s?  Cuz I’d never heard of it that way before.  Must’ve been in day treatment in 1981, in a group, that a lady referred to herself as having “gotten sick.”  She was referring to depression.  I had never thought of my eating problem as a sickness before, and now, it was being presented to me as some sort of medical problem.  Maybe now, if I thought of it like that, it would be like a cold or flu, something you stayed home from school for, something that people gave you chicken soup  or flowers for or a get well card for, something people said, “I hope you feel better,” for.  No, I wasn’t crazy or bad.  I was sick and everyone should feel sorry for me and now, I had a damn good excuse for dropping out of living.
