Are we surviving the terrible twos??

Is anyone only one month deep in the terrible twos (she's only 1.5) and just completely struggling?? She won't stop hitting, hair pulling, being defiant, testing literally every boundary, and throwing. Idk what to do. I've tried channeling her energy into other things. I've tried saying that's not nice. I've tried taking her hand and putting it to her side and saying we do not hit. She used to be the sweetest and most perfect baby. Now she's a little terror
