Narcissism isn't just about someone loving themselves - it also fundamentally concerns their predisposition to take over and direct the lives of everyone around them. Their tools are virtually super-human abilities to stealth-interrogate, construct fairly (and terrifyingly) accurate pictures of events based on seemingly disparate and minute 'bits' of information, and just how to clinically analyse, approach, and break down others' strengths and defenses for personal gain.
The OP worries about feeling selfish, so understandable considering how much of their own power has been overwhelmed by peers bent upon control.
This is not selfishness, though - it is the
feeling resulting from being manipulated by another.. and the need to reestablish personal control.
The Narcissist convinces us that our bad feelings are guilt, and are
our fault, drawing in - and conditioning - all who are vulnerable to a super-humanly strong will and motive.
You are not weak,
BoN-bOn, just the victim of predators!
Bless you for the amazing individual you are!
