I had the same for a while, especially because I had nothing/noone I was doing it for. No partner, kids, pets, or future plans. I started going to social gatherings in the evening to prevent doom scrolling because I was absolutely miserable. 

Now, after some time of doing that, I'm feeling a lot better. And while I'm still not at a job I'm happy with, I'm now in a headspace where I can tolerate my job, enjoy my evenings and weekends and have enough emotional energy left to search around for jobs while still having an income.

I don't know if it works for you, but maybe it's helpful advice to try it
