Hey so I have been working at this company for 14 years and over that I have probably had around 3 weeks sick days off over 14 years, I managed to catch covid a week and a bit ago so have been off for a week and started tested negative 2 days ago so was going to go back to work tomorrow, today I had to go to the hospital as my chest was really painful and it turns out I have scarring of the lungs from covid and they are sending me for an check to my heart so I called up apologising saying I wouldn't be in and I know we are really really short staffed we are a team of 4 down to 2 now tomorrow and the guilt is eating me alive, I hate the though of my lot working harder to cover for me has anyone got any ideas how to stop this feeling?
