Good luck OP. No harm in taking a break out and doing a simpler job. It’s funny, as I often think about retraining (well I used to, but nearly into mid 40s, so I’ve missed the boat I think) in law. Reading posts from lawyers on other threads (and talking to lawyer friends who work in private practice) has made me rethink.
FWIW, I’m a B6 nurse in the NHS…nearly 27years under my belt. Obvs no need to monitor/bill my hours, but plenty of unpaid overtime and other crap (abuse, short staffing etc). Choose something you love to do, and hopefully you’ll feel a lot happier :)
