Will you feel relief if you hand in your notice?
I keep wanting to try that out, "imagine you'd handed your notice in yesterday, how would you feel this morning?" but I don't want to con myself and have to deal with it not being true(!). I think I'd feel huge, huge relief and a bit of glee at them having to deal with me leaving (which is not good karma).
By this do you mean that you're leaving to be self-employed and have a business plan etc or do you mean that you want to do something different and be self-employed but don't know what that will be yet?
The latter. I spent a couple of years retraining in all of my spare time, but that hasn't worked out and I think it's a dead end. I wanted to build something up so I had something to go to, but I think I'm just completely worn down that I don't have any zest left.
Is your profession something you could easily get back into if you change your mind / get desperate (eg teaching in an in demand subject)
Oh yes
there is always that but it'd be Plan F.

Thank you everyone, there are so many more comments that I want to respond to, but my head's spinning (am currently avoiding being at work). Yesterday evening was difficult and I'm thinking of trying to get an appointment with a doctor for a couple of weeks off.
