I think that, to some degree, people are mixing up physical energy drain with psychic energy drain. Yes, they are intimately linked, but there are also very different actions going on, with often completely different causes. You can have physical energy drain by being physically sick. This is at a chemical level, and won't be corrected until the physical problem is corrected. On the other hand, you can be perfectly healthy physically and experience psychic energy drain...created by yourself or others. Your own strong emotions can drain your psychic energy...as in becoming angry. Blaming that on another person, "he/she made me mad", will bring about an instance of you being the cause of leaking your own energy. No one can make you mad, that is a choice that you have made. If someone is around who will soak up that energy, it's still not always the case that they "sucked" it from you. You gave it freely, probably unconsciously, but you made the choice to become angry.
