When I wasn't drinking I was busy storing all the things that I resented greatly and was angry about. Then, if my husband even looked at me in the wrong way or said one little thing that I perceived to be off kilter the storage bin would open and out came all of that anger. I said some pretty horrific things. This, all from a person who would do anything for anyone.
I have a feeling that it was due to my resentment due to my codependency when I wasn't drinking. There were things that I said that were completely not true but the anger was real, for certain.
