i'm sick of this

was just venting to this guy and he pointed out i showed strong signs of NPD. i was like "no way" at first but once i read some articles i started to doubt if my behavior was really normal or not. now i don't want to be like those people who self diagnose themselves to be different, so i've considered getting a professional diagnosis, but none of that shit is available to me without my parents knowing. i swear with my life my parents will not believe that i need a diagnosis and they'll probably brush it off like i'm delusional. i mean i have so much of the symptoms for christ's sake is online threads really supposed to relate that much or am i just behind dumb?
