Sharkopus's journey

I am currently in my last week of work at an IT company in Quebec, Canada, where I've been employed for 8 years. I gave my two weeks' notice the Friday before last week and took PTO last week, which I had reserved back in February. Now, as I prepare to return for my final week, I'm feeling really anxious and unmotivated. The reason for my departure was the toxic management in my department, which is notorious for not rehiring former employees and not providing references. I know that many of my colleagues are also looking for new jobs, and I feel fortunate to have been able to leave first. However, I still need this week's pay, so I can't just not show up, but I feel conflicted about clocking in and doing the work. I'm seeking advice from anyone who has gone through a similar situation. Thank you.
