Emotions
Naming what you feel changes what it does
"Fine" and "stressed" are hiding places. Precision is a form of relief.
Most of us work with a small emotional vocabulary: good, fine, tired, stressed. It is efficient and almost entirely useless for understanding yourself.
"Stressed" could mean overloaded, or unprepared, or resentful, or afraid of being found out. Each of those needs a completely different response.
Naming a feeling accurately does two things: it lowers the intensity slightly, and it tells you what the feeling is asking for. Overloaded asks for fewer commitments. Afraid asks for information.
Try one sentence a day: "Right now I feel ___, and I think it is about ___." You will be wrong sometimes. Being roughly accurate beats being vaguely fine.
