All on e can do is (a) search earnestly for a better job where you would be happier, and (b) see a psychologist / counsellor for help in dealing with your anxieties better, so as to be less distressed while waiting. And this could also identify WHY a situation like this is so specially distressing for you, as maybe some changes in your expectations would help, and understanding it better could prevent you landing in a similar situation in some new job.

Some months later, a very mucch better job opened up within a different branch of the same organization, and she was able to apply and get it - which she would not have done had she just left.
