I'm off today with tonsillitis having had no time off for maybe 10 years. My company is OK with absence and boss is nice, but I feel so guilty about the impact on my colleagues as it will be a huge inconvenience. I've not slept and got horrible D&V which I think is the anxiety of being off, effect on my colleagues, no-one picking up my work and returning to an even more enormous mountain. Obviously there's been a lot of absence over the pandemic but my job is one of a kind and other people are in teams. I did think about going in but I can barely speak or swallow and my face is all swollen which would frighten everyone.
Any tips on trying to relax and get better? I realise it can't be helped and I'm being irrational.
