To be scared witless as I am about to go into work tomorrow

[sickoftheemails]

and hand in my notice with no job to go to

Life, even.

I did this and never looked back. But I'd managed to save enough to cover mortgage and bills for a few months so I felt a bit more secure. But if work is awful then go for it. I would add, have you considered being signed off due to stress? A time out might make things clearer.

a friend of mine did this earlier in the year, walked out and couldn't go back. She got a new job the following week! Do it, life is too short to hate what you do. BTW what do you do?

I've done this, and believe me you cannot put a price on your mental health. If it's that bad, don't think twice, just do it .

Line up a job before you hand in your notice if you cannot live on one wage. The job market is pretty awful at the moment and you are more employabe if you are in a job.

Even if you hate it, you can check out mentally once you know you are looking and will be moving on soon.

Did you resign then?
