Looking for a webtoon? manhwa?

Idk if it's a webtoon or manhwa but it's something along those lines

I don't remember much but it's about a girl with black hair (shes very pretty) who is bullied extremely hard in her high-school and for a while she just tries to ignore it but eventually tries to kill herself by jumping off the roof of her school (if i remember right the first ch starts with her about to jump, but idk). We see her mom is like a witch? (But the korean version of a witch?) and i think that's the reason she was being bullied (but maybe not) and it's eventually revealed that the girl is like a god or part of a god, something like that and she starts using her powers more? I know they had something to do with hurting her bullies, but whenever she did it there was another negative affect

That's all I can really remember sorry the details are so poor, idk if i read it on here or another site it was a few years ago. If you don't know where to fined it but know the name that would be good enough thank you
