In short im currently off sick following surgery but due to return Monday. Have been off 4wks. 'D'H has announced today he is unhappy and would like a divorce and has promptly upped and left to stay with his sister. There is no way I can put on a brave face at home and work and I'm considering asking for fit note while I try navigate this situation. I don't want to lie to work or gp - physically well enough following surgery but now emotionally on my knees. Does this count as a second period of absence? Can I be off sick for a different reason without returning from 1st episode? Any experiences would be appreciated!
