Go to the doctor and talk to them about this.
At your job, I hear that your manager won't meet with you for one to ones. I'm not sure about the size of the organisation but is there a HR person or a manager of your manager with whom you can raise these issues? Or does it stop at your manager? I'd be interested in any advice here from people with HR expertise about the best way to manage this. I'm sure you can evidence a lot of your points so I wonder if it would be useful to pool all that evidence into one folder that you can share with the manager, copy in the Chair, HR, the CEO, whoever's relevant.
I know someone who is off with stress at the moment and I completely understand why, they were excellent at their job, then were given more responsibility, a slightly different role and more pay. They were brilliant at this but for financial reasons that opportunity ended, they were made to go back to an old role at lower pay BUT with all the additional responsibilities and none of the time to do it in. All of this during a period where they experienced something devastating in their personal life too. We work in the same sector so I wasn't just taking their word for how good they were - it was from co-workers and other industry experts. The organisation has shot themselves in the foot by losing this person from the team. They are currently evaluating a career change. They visit a counsellor and they're using this time to recalibrate.
Have you read or listened to The Let Them Theory? I know it's all a bit cringe but I think you could benefit from some of the approaches and advice in there (I got the audiobook free from my local library). Work's being a dick? Let them. But that doesn't mean that you just enable them to make your life shit. You've also got to "let me". You can't change their actions so what can you do? Where is your power in changing your own life and circumstance?
This is where you act:
- you collect the evidence to make the case that they haven't been fair.
- you go to your GP to talk about stress and anxiety
- you listen to your supportive empathetic husband who has your wellbeing at heart when he says you can get by on his wage for now
- when you're ready, you look for training or alternative jobs so you can make the move away from this job and use your talents and skills somewhere that appreciates you
Your mum sounds like she's maybe had a gutsful of listening to your negativity around your job and is maybe of a generation and mindset that you should pull up your bootstraps, suck it up buttercup and just crack on. That doesn't mean you have to do any of that. That's how she feels about it. OK. You're an adult, you're a newly wed (congratulations!), and you have power over your own life.
What do you want for your life? Work on that. Don't waste your days in misery. That's easy for me to say. Your mention of feeling hopeless and not seeing any other way makes me agree that you're probably also depressed and that's something to talk about with your doctor too.
I've done a fair bit of recruitment over the years and don't give a rat's arse about gaps in CVs, I care about what the person's experience and skills and character bring to the role, I care about our visions aligning.
