They're often called emotional vampires/ toxic persons. I think that most of us know atleast one? How do you deal with them?

Spending time with them can leave you feeling drained, unmotivated, and depressed.. thats how you identify them. You might even crave comfort food or feel like taking a nap.

I've found that the control-freak and/ or narcissistic types often find ways to push your buttons... often deliberately attempting to "pull the rug" from under you by touching on areas of shaky self esteem. Most therapists/ experienced people tell you it's for the best to to limit time around them or cut off contact. For a good reason being around them basically sucks your positivity and worse still their negativity is infectious, you end up replaying the negative interactions in your head, creating ill emotions and complexes.
