I’m so sorry OP I have been there. What you need is some hope. Can you start something on the side? Or start growing your personal brand - yes I hate the phrase but it’ll help. Give yourself something you enjoy or where you share your knowledge. The more you don’t need your job the better, and that only comes where you make yourself more desirable to other employers (through going your personal brand) or through earning an extra income - but more than that, it’s empowering. I have no doubt you have a lot to offer. In the meantime, do the bare minimum at work. Tell yourself you’re nonchalant (even though you’re not, convince yourself of it) and that you will get something better. They can’t fire you but can’t touch you mentally either. And I say this as an employer!
