Feeling like a terrible awful person

A reader asked:
I’m sorry if this is a stupid question, but it’s gotten pretty bad… whenever I have a moment to think– usually when I’m laying down for bed– my mind defaults to thinking up every single reason I’m a terrible awful failure who doesn’t deserve to exist, and it ends up causing a sort of feedback loop that magnifies those feelings a hundredfold. Do you know anyone who does something similar or might have some advice for breaking the cycle? TIA.

This isn’t a stupid question. It’s a hard situation to be in, and you’re definitely not the only one.
For me, it helps to have some TV episodes of a show I’ve seen before and like playing in the background when I’m going to sleep. That way, I don’t have totally blank space available to be filled with that kind of thinking.
I also have friends who can help me remember that I don’t actually suck when I’m feeling that way. And at this point, I’ve had that conversation with them enough times that sometimes I can think through what they’d say when I’m in that state of mind.
Some people like things like Calming Manatee, or other cute animal with a positive message sites. That doesn’t work for me, but it does work for a number of people I know.
There are probably better things to do that I don’t know about. Do any of y’all have suggestions?
