If you observe any of these behaviors in people around you -- whether a partner, friend, or co-worker -- it's an unequivocal signal that you've got a toxic problem on your hands -- no ifs or buts about it!  1. They consistently make you doubt YOUR  own reality.  Better known as gaslighting, if someone twists facts to make you feel wrong or crazy, that’s manipulation, not miscommunication. Trust your instincts and know when to call people out on their BS!  2. They celebrate your failures or secretly root AGAINST your success. A real friend or partner supports you. They want you to thrive irrespective of their own successes. If someone revels in your setbacks, however, they don't have your best interests at heart -- they’re just plain toxic! 3.

Other words associated with narcissism include: Self-love Self-admiration Self-absorption Self-obsession Conceit Self-centered Self-regard Egoism  I don't take exception to people who are self-absorbed without showing off . It's when people have the impulse to voice -- loudly, I might add -- how great they are, how beautiful they are, how much better they are than anyone else. It's when people are so arrogant as to take credit for everything -- whether at work or elsewhere -- when they know full well that they received ample support from others.  Selfishness isn't necessarily a bad thing.
