AIBU to leave my job?

[AuntieMeemz]

I'm an older mum, well educated but not very clever or shrp by today's standards, doing a job I'm not good at. There is something wrong with me because I just keep on making mistakes no matter how hard I try.
I had a month off with stress, and returned to work yesterday. My line manager has been really shitty towards me. No single issue I raised has been addressed, and to top it all, despite working in a very intensive, process driven job, working under pressure to deliver to tight deadlines, I got a lousy appraisal that only listed my mistakes and ignored the huge amount of work I've done well.

Yes I think you should hand your notice on before you're 'managed out'.

And then find a job which suits you better.

I wouldn't leave until I had another job (unless it is affecting your health)

it really is easier to find work when you are in work

Agree with AnyFucker.

Start shopping but you are in a much stronger position if you have current employment.
