If I start down the road of "I need to be earning money," I try to comfort myself with something like, "I've never run out of money yet." Then I have to go through asking myself whether, if certain trends continue, I will break that trend. Then I actually have to accept that I might run out of money. And I have to think through the possibility that I will lose my house and any other assets I have, and actually have to deal with homelessness. If I did actually have to deal with homelessness, it would greatly increase the possibility that I might die sooner than later.
Actually, all of my anxiety-dealing gets around to dying.
