This internal variation is pharmacologically dependent. Changes in a persons pharmacological makeup can cause mood changes, sleep disturbances, and even depression. The I-function influences mood manipulation but cannot determine mood. Though you may want to be in a good mood, make a conscious effort to think RhappyS thoughts, and may not have serious stressors in your life, you may still suffer clinical depression as a result of a chemical imbalance in your system. Depression can be physical and chemical and can be caused by things totally unrelated to the I-function and personal thoughts and experiences.
Clinical depression is characterized by a list of symptoms that last over a long period of time.
It is a serious problem that is usually, initially caused by outside stressors. These stresses escalate and eventually result in a chemical imbalance. Clinical depression can be very dangerous and can even lead to death that the depressed person may bring about by their doing. By analyzing many of the symptoms of depression, I was able to make more sense of them and was able to relate them to other generalized control mechanisms. This analysis also helped me to see the aspects of both sensory input and chemical imbalance in depression.
