Some people definitely get addicted to their emotions, partly because of the point stated in the article: they don't quite see how emotions can be manipulated. They accept their emotional states as given since they cant perceive the difference between their egos and their true selves.
I was in a relationship with a person who suffers from chronic depression. He would never leave the constant circle of thoughts that keeps him at his depressed state. When I tried to explain him how thoughts fuel emotion and how change of perception can change emotions and experiences, he would not understand me, and I got a feeling that he actually does not want to understand me since he likes it where he is. It is certainly a psychological addiction though, but I can clearly see the pattern of smokers/drug abusers: I want to quit but I can't get over it. And on it goes...
I am certain that emotions can be fully manipulated by means wolfgang describes. They are basically ego's unconscious and habitual reactions to past situations. I used to be (to a lesser degree than a depressed person, but still quite a lot) addicted to emotions, fueled by loads of negative past experiences. I would not see the difference between them and my true self and allowed them to fully control me. Needless to say, there were highly destructive episodes. But at a fairly recent point of my life, I put out a strong intention to improve myself (I did not even know what intentions were back then

) I found this site and got to the book Power of Now. Now I am practicing the ideas of this book every day and feel that my emotional states have changed a lot. Whenever I feel a sudden rush of anger, sadness, low self-esteem, fear, I detach from it and observe it from the standing point of Now. I even visualise myself standing in "Now" much like a tree

. The harmful emotions always go away within seconds. I always allow myself to experience joy/love/passion fully. My life truly has changed a lot for the better from this practice.
