I'm not talking severe stress, or clinically significant anxiety depression, etc. More 1-4 out of 10 tension, irritability, worry. Whatever words you want to put on it. Low level fight /flight.
I'm very rarely calm and settled. Most of the time it's in the evening watching TV with DH if it does come.
Tbf I have had a very stressful life. Since I was born basically.
If you are generally calm did you have a good childhood?
