I have a just turned 3 year old and I'm now coming out of this stage (thank god!!)
My then 2 year old son would scream and scream and scream. Didn't matter where we were, what we were doing, if I told him no, he would throw himself on the floor, roll, kick, scream, shout, bite, punch etc.. I tried everything (bribing, shouting, walking away)
The only thing that worked for me? Ignore it. Completely ignore it. If we were home, I'd put him in his room, tell him he could come out when he could behave and walk out (child gate on) it took weeks and weeks because I, stupidly, wasn't consistent to begin with; I'd give in after a few minutes, or shout.
It was horrible to hear him so distressed, sometimes he'd cry so hard he'd retch but he quickly realised his behaviour was totally inappropriate.
It might seem harsh to some but a few months later and he's like a completely different child! I would even avoid going out in case he kicked off.
Please don't give up or lose hope, I was exactly where you are and never, ever thought I'd get through it
