What does it mean when I get angry during working out?

Hi, I don’t know if it’s a psychological issue or a physiological issue, but when I work out, especially running, I tend to develop a great deal of testosterone and become very angry during the run. Afterwards, I do not feel this sense of “elation” that many people experience during and after a workout.

Does anyone have any idea why? It bothers me because I don’t want to work out because of that. I am healthy and in good weight. I maintain my weight through cardio and strength training.
