So, yes, these people are vampires, and yes, they can exhaust your energy and have you feeling very tired and very ill. However, one needs to feel for them because at one stage of your many lifetimes and incarnations you were like that also. I was born to give them my energy and to, in a sense, feed them so that they can lift themselves out of their darkness. If you were born with Chiron in the first house of your natal chart or Jupiter (and I have both), you have come to heal these people either collectively en masse or individually.
President Obama has Chiron in his first house and he has said he wants to heal the darkness in the world. If you attract this kind of person into your energy and you find that they exhaust you, then by all means do walk away from them. Many of your parents and close friends are like this and it makes it so hard to walk away. However, it is either them or you. Think about that. Sometimes it is necessary to sever the ties if your health or well being is at stake. However, try to find someone to send them to who can help them. Don’t feel guilty because you walk away.
I have met some amazing healers who are so bogged down in their own darkness that they wonder why they cannot get clients, yet they cannot see their own darkness and get offended when they are told they are in darkness. If you have great energy and you are emitting light, then those who need you will find you. I have never wanted for work and I put it down simply to the fact that I have lots of energy and lots of pep to give to those who need it. I also have that Chiron and Jupiter in my first house. More than anything, do not run away when someone’s energy affects you. Either send them to someone who can help them or find out why their energy does affect you!
