And wonder of wonders, PA does actually allow a medical quit.

Medical Reasons: When you cannot work because of a medical condition (or when working would worsen a medical condition) you may have good cause to quit a job, and could therefore receive unemployment compensation (Deiss v. UCBR, 475 Pa. 547 (1977)).
To receive unemployment compensation after quitting a job for medical reasons, you must show that:
You had adequate medical reasons to quit your job; and
Before quitting, you told your company about the problem, and gave them a chance to accommodate you; and
Even with the health problem, you are able and available to work at some job.
At your unemployment compensation hearing, you may need documents proving that you had a medical condition (Wivell v. UCBR, 673 A.2d 439 (1996)).

(And I'm not sure how relevant that is to the OP - but I did find it, so maybe someone else can benefit)
