I have another job lined up and start in a couple weeks. I have not given my current job notice yet as my direct manager is away on vacation. I have been miserable at this job for a long time and am changing careers entirely. I still feel like I should do my work and perform as if nothing is changing but I don't want to. This is my one chance to stick it to this company and show them you can't treat employees like shit. Is this a weird form of Stockholm syndrome? How do I convince my brain that nothing at this job matters and to just enjoy not having responsibilities?
