My bestie's grandma hates me

My bestie started to text to me this morning that since the day i went out with her(and other ppl) her grandma started saying bad things about me, It started with absurd things so i just laughed It off, for example, she thinks my bestie is giving me money....for some reason?? Like thats some absurd paranoia!!!! I know Im broke but I never asked for money or talked about it near her.

  Then she started saying worse things after, like.... how she doesn't like that we are friends, just because Im queer AND she even thinks we are dating brooooooo what the hell!!!!!!!!!!!!! 

  Thats not all, my bestie said to her that I was working, to counter the argument that shes giving me money, right? Do you know what her grandma said? The shit she said? She said "working? Must be stealing, i bet." Fuuuuuuck Im so fucking mad, thats when I got mad for real!!!!! Im still in shock like wtf!!!!!!!!!!!!! 

I give 0 fucks to what people think of me but that? How the hell would she perceive me like that? Is it because of my skin? Is it because Im poor? Theres no fucking way someone would think that about me by looking at the way i act.

Sorry for the rant, I had to take this rage off my chest, felt like exploding.
