The brain has one job. To keep you alive. It isn’t your friend. It will do anything to try and keep you safe. It’s a worry machine.

It is safer for you to worry about how you talked to Phil last week because thousands of years ago if Phil didn’t like you, you may be kicked out of the group and humans living alone are much less safe.

If you cut yourself, you need to remember how not to do it again.
