I’ve had a recent experience which has left me feeling very similar ...
Loved my job, senior position, worked very hard, exceptional results and feedback over several years, well liked etc ... some changes at the very top led to toxicity filtering down and I spoke out about feeling bullied.
I had evidence, lots of it, complex Very unpleasant situation. It ended in me signing a NDA and walking away with a settlement.
This rocked the very bottom of my world. I never imagined I would ever find myself without a job without resigning with something else to go to.
It’s changed so much for me and left me feeling incredibly insecure, like nothing is for longer than today, anything could happen outside of my control and I would be asked to leave again or made redundant, or sacked now I don’t have the two year employment protections.
When I left I applied for minimum wage call centres as I actually believed that’s all I could get ... it’s been 3 months but I now have an amazing new job where I’m learning new skills, people are kind and i feel okay there.
I’ve also turned down 4 other offers, for decent jobs ... I’m still terrified of being unemployable and destitute forever.
Over these last months I’ve saved every penny.. I’ve spent no more than £100 a month in addition to my basic bills (food inc in that 100quid) as what if I’m unemployed for years ...
My mind runs away with me and I’m just so scared as I’ve got another 30 years of my working life.
It’s got so bad for me I’ve seriously planned ending my life as it’s too much to manage.
It’ll be okay, it has to be!
So sorry OP, I just know how hard it is
