2 year old tantrums

My daughter is 2.5 years old. She turned into a different kid right around 2. I know it’s normal to have tantrums and lots of them but I’m at a loss on how to deal with them. It’s literally about anything. She screams and screams and nothing works.

I’ve tried ignoring her, redirecting (which she just screams louder), screaming back, speaking softly, time outs, literally everything I could read about.

I know she’s figuring out emotions lol but I don’t know how to help her. She screams and wails in the car, any time she’s told no or to stop, when something isn’t done right when she asks for it, etc etc. it’s so frustrating. She’s also in the “mine” stage.

Any advice is appreciated. She is my first and I’m currently 30 weeks with my 2nd and waiting for her to grow out of this 😅
