Feelings are just feelings and NOT facts was one of the top lessons I learned in Al Anon.
It used to be that my feelings told me things all the time that I chose to believe as a truth:
I feel fat
I feel unworthy
I feel suspicious
I feel anxious that something horrible is going to happen
It was also enlightening to learn that feelings aren't good or bad, they just ARE. I was brought up to believe that anger and pride were BAD feelings. It's not the feeling that is "bad" but rather what we do with them.
My feelings used to lie to me all the time, back when I thought they were defining me, giving me my truths. Now I know they are just feelings.
