Background is that I was in my last role I had a highly toxic manager, insane workload and pressure. I ended up ill with stress and eventually leaving with a large settlement for the poor treatment.
For the last few months I've had some time off to recover and have then been working part time, in a short term contract, which has been fine.
I've applied meanwhile for a bunch of other stuff and have now been offered a role and have accepted it. It basically ticks almost all the boxes and is well paid and the people I met seemed nice. Starts in a few weeks.
However. I'm feeling incredibly anxious and stressed in a way I haven't for the past few months.
I feel like it's almost inevitable that I'll fail because there are things I'll be expected to know how to do and don't. And that I'll clash with my manager. And that the corporate culture will be a poor fit for me. And the work life balance will be bad, I won't see my kids enough and I'll burn out again and just be miserable. And no matter how bad it is I'll have to stay for years so it doesn't look weird I left.
Realistically, there will be things I don't know how to do and it will be hard, because senior level jobs are like that. I guess that's normal.
But I don't know how to reign in these feelings that are obviously coming out because of the terrible experience I had last time, and how to stop them sabotaging this role.
