We each feel some degree of anxiety, anger, and depression every day. Our emotions vary moment to moment. That is also normal. Frequently, these intense emotional transition periods are periods that help produce our greatest growth. So they are periods of great opportunity.
Emotions serve as warning signals about underlying issues .
The main positive function of the negative emotions is that they tell us that something is wrong. There is a mismatch or conflict going on in our cognitive system. Our goals, expectations, plans, perceptions of reality, or other thoughts aren' in harmony. Some part of ourselves is not getting its values met at the level it expects. Similarly, if someone you love starts giving subtle messages that he or she is tiring of the relationship, your inner lover might get upset.
