Psychic Vampires, or those who drain the energy of others, can be found anywhere and everywhere. And if you're empathic they will be drawn to you like a moth to a flame.
It took me many years to develop effective ways of dealing with these individuals. And I've found that I must remain vigilant. Countless times I've given a psychic vampire the benefit of the doubt and then paid dearly for it.
If you are dealing with a psychic vampire it's vital that you understand that they are unlikely to change their behavior. Draining others is how they get their energy and I guarantee you that their wants and needs will come before yours.
The best way of dealing with a psychic vampire is avoidance. If that is impossible then you have to strengthen your energetic boundaries. This can be a challenge if you are used to putting the needs of others before your own.
I have recently found two resources that I've had great success with. One is a wonderful book by Christiane Northrup called Dodging Energy Vampires. The other is a hypnotherapy recording by Anna Thompson called Power Shielding.
I wish you much success in dealing with your psychic vampires.
