SueEH, I was in a similar position 18 months ago but with only 1 job. I had returned from sick leave just at the start of lockdown and was bullied by my head of service. I stood it for nearly a year then decided I’d had enough and that I didn’t need to work financially. I have worked since I was 16 and was more than capable of working still so it didn’t sit right that I should just pack my job in. Friends told me life was too short, that I could get voluntary work, and because my husband (13 years older than me) had retired we would do all sorts of things together and go away whenever we fancied etc etc. For me the reality has been different. I miss the discipline of work, but you will still be working for your friend; a lot of voluntary work around here is either in a charity shop or befriending over the phone, neither of which appealed; my husband won’t plan any days or breaks, it’s up to me to come up with ideas all the time and it gets a little wearing. I am bored BUT I’m a lot happier and laid back and the issues I have, I have control over.
Pack in the job you hate with a clear conscience. Give yourself time to decide what you want to do, whether it’s paid or voluntary. I’ve found that I spend less although I go out more because I might meet friends for a walk or a coffee rather than a meal.
Good luck.
