It is impossible to separate your mind from your body. What you feel physically will have a direct effect on your emotional self. This is also true of your emotions. If you are upset or under a great deal of stress, your physical being is directly affected, usually in the form of pain. Attempts at controlling emotions create stress.
Stress increases pain.
You have no control over what you experience emotionally. You can only choose how to express those emotions. There are no wrong feelings. Your feelings are as much a part of you as your arms and legs. Accept them, recognize them, and learn to deal with them to reduce stress and tension.
