Hi, I’ve just joined Gingerbread and was about to make a very similar post! So safe to say it’s really not just you. No advice as I am right there with you but sometimes it helps to know you’re not alone in how you are feeling!
I’m considering switching careers into a lower paid role where I can just work a set number of hours and switch off.
In the meantime, burnout is a justifiable reason to take sick leave. I recently took a month off due to burnout certified by GP. Give yourself some time to get your head above water if you can.
