Ask HN: How I can get out of a job that has me burned out and exhausted?

Four years ago I started a job and it was pretty good at first. But due to some corporate changes everybody just got slammed with work. Upper management does not think it's wise to hire more people so they are burning everybody out and people are leaving. The workload is unmanageable and it just never ends.

It's time to move on but I am just too burned out. I have even recently caught myself forgetting pretty basic stuff. My weekend are just spent recovering from the week really. I don't do much activity that I used to for fun because I am just so tired. I asked my psychiatrist and I am not depressed.

Any advice?
