Same here.... I was let go from my job because I ran out of medical leave. I attempted returning and lasted 3 days. (I worked with teenagers with emotional and behavior support issues).
I am back to grad school part time and for have to do an internship in a preschool. My drs are only allowing me to do 12 hours a week and it's killing me. And I really want to be back with the older kids and I don't know if that will ever be possible.
When my company let me go becuase I ran out of medical leave I remember feeling the rejection and pain you feel. It sucks when you are so loyal to your job and love your work and they can just let you go without a second thought. It still hurts...
Atleast you are guranteed something to go back to? But I know that probably doesn't help you feel any better now.
So sorry you are having to deal with this. There are many of us who have been there
