Feelings are not facts. My feelings can be stirred as much by imagines as by real causes. Between a feeling and a fact there is always some (at least implicit) thought; and the more disturbed I am the less my feelings are related to reality. My chief task, therefore, is to keep my thinking true and my behaviour sound, and to go by what I know, not by how I feel.
It is from the Blue Book which is a book of things like that. It is part of the GROW program which is a mutual help support group that originated through mental health recovery but has extended to assist anyone going through difficult times. I don't know where you are but you might like to google it and see if there are meetings in your area. It helped me greatly for about 6 months.
