Wrapping it up
A narcissist is dependent on a regular, continuous flow of narcissistic supplies. They rely on it to sustain their superficial self-image and feed their ego. People in interpersonal relationships with such individuals are merely used as a means of an extension of their self-serving needs. If you feel like you are being used as a narcissistic supply, it is important to remember that you are not alone and professional help can always guarantee you getting out of such relationships, both physically and emotionally.
