Every emotion that you feel, is literally communication that is offered from your Inner Being. Because you Inner Being has access to all points of Energy throughout your apparatus, many physical sensations can be effected in your body by your Non-physical Inner Being.
In the same way that you have “feeling” sensors in your fingertips, to protect your fingers from sharp, or hot, objects, your Inner Being often evokes feelings or emotions within you to guide you. The discomfort of pain in your fingertips brings forth an impulse to act that prevents you from greater harm - and in the same way, negative emotion is offered to guide you away from that which is not of value to you.
You have come to define your emotions in very broad and detailed terms, but technically there are only two emotions. One feels good, and one feels bad. And these emotional feelings are present because your Inner Being has offered an impulse that has triggered the physical response within your physical apparatus.
Your Inner Being is eternally aware of you, here in this physical body, offering guidance in the form of emotion to help you know - in the moment of the emotion - whether you are moving toward or away from that which you want.
