If i feel im forced to quit for medical reasons is there any possibility of compensation?

Hello, I have a bit of an odd question to ask. I've been battling some sleep related issues and after my most reason visit to my sleep specialist i was advised not to drive anymore. After speaking with my company's hr rep I was informed that my time off work would not be covered by my short term disability and if I had to take time off work, being i was not employed for over a year I would not have a job to come back to. At this point i turned in a written 2 week notice to seperate from my employer as i felt it was my only choice. Three days after i turned in my notice i got a call from the head of hr and was informed they will not need me to work out my notice. Can anything be done or should i just cut my ties and move on?
