Tik tok song

help me to find this song, I think was r&b it gave the same vibe that kill bill by sza, I heard in a tik tok trend were people told stories about their crushes like crazy things that they did (but is not crazy by Gnarls Barkley bc both songs had a similar trends) this one is sung by a woman and I remember that the music video on YouTube was the singer recording herself, it seem like a video on a loop of her face and the lights were pink, I don’t remember the lyrics but she said some thing like “I’m crazy” , “bossed“ or “I’m going crazy“ basically she was telling that she was in love with this man and made crazy stuff for him or something like that. help me please
