Potty Training

I'm 24 yrs old & a mother of 3. ❤️ My oldest is 2 yrs old and I'm having a hard time trying to get her to use the potty. She hates being in dirty diapers so she tends to just take it off, but she will not go use the potty. I've had multiple times where she goes #2 in her diaper and doesn't tell me she needs a changing so she just rips it off & I find the poop everywhere. 😭 I've tried bribing her with candy, I've tried reading to her, I've tried awarding her even just for sitting on the potty. but nothing is working. She aware of how to sit and flush but every time I try to sit her on it she throws the biggest tantrum I've ever seen her throw. she screaming at the top of her lungs, like something you hear out of a horror film. I'm so overwhelmed trying to figure out a way to get her to calm down and just sit for awhile. please help. any advice at this point is greatly appreciated. 💔😩
