I googled, and found this:
Look in the mirror?Sometimes we are the Vampires. If we pay attention to our thoughts and words we can eliminate the Vampire in us. Are you being negative or positive? I ask myself this often.
Confront and Reform-Tell your Energy Vampire (EV) that he or she is being negative. They may not even realize it. Ask for support, positive feedback and encouragement from them. If your EV is a colleague, family member or friend, perhaps you can reform them into an Energy Addict. Show them how to spread positive energy. If they just don?t see it or refuse to do it then you may have to give an ultimatum. You might say, "This is my goal. This is where I am going and if you?re going to be negative then I can?t be around you.
Turn on the Light?When you were a child and scared of the dark you turned on the light and felt better. Negative energy is like darkness. When you encounter an Energy Vampire, turn on the light. When an EV comes at you with fear, negativity, hate and anger turn on the light and respond with love, kindness, and positive energy. Negative energy is powerless in the light. Think about what happens when someone gets mad and yells at you. If you don?t yell back they lose momentum and power. If you return with kindness they lose even more power. On the other hand, if you yell back at them then the negative energy grows and grows.
Run?Run as far and as fast as you can. This sometimes is the best technique if you are not close with the EV. You only have so much energy and in today?s world you need to keep all you have. If, for example, you are in the grocery store and you see someone who drains your energy then run away fast. Really fast.
