i've been hated on in the past; i still get it today. the difference between now and then is my mentality. before, i would think that it had something to do with me, that it was my actions or whatever that caused others to hate on me. now, if i'm hated on, i realize it's not me at all... it's THEIR problem and THEIR own insecurities coming out.
now, people here might think i'm an *******/jerk but i am not. i treat everyone w/ respect and i don't talk ****. if you are a genuinely good person, and people still hate on you, they're jealous.
oops, i just realized i didn't answer your ? how do i handle it? oh i wish i knew this years ago! this is how i handle it:
BE UNAFFECTED. haters want to see a reaction from you. if you react, you just gave your power away. but if you brush it off and act as if their negative energy has absolutely no effect on you, you still hold the power (i said act "as if," because from my own experience, @ first it was hard to simply brush it off.. but surprisingly, i continued to act "as if" and eventually negative energy from the haters really did not effect me at all)
