The same thing happened to me. i didn't take enough time off bc gp also said i would be fine. i was not fine. i ended up crying at work all the time. i could not do my job. i ended up getting a note to stay out of work longer. in the end i got fired which was for the best because then i got unemployment. it was no where near enough but at least i could eat and keep the lights on. i did not return to work for over a year. i wiped out all of my savings but i could not have gotten better if i were still working.
