A scale tips toward what’s heaviest. Your mood tips toward whatever you think about most.

Whatever gets most of your attention sets the weather. You do not choose your feelings directly, but you do have some say in what you keep turning over, and a mind spent on one worry will tilt toward it by the afternoon. That is mechanics rather than weakness, and mechanics can be worked with.

Notice what you have been rehearsing lately. If it is the same conversation on a loop, put some weight on the other side: a walk, something you are good at, somebody who is easy to be around. You are not banning the worry, only refusing to let it be the only thing on the scale.
