Toddler hell?

Anyone else going through hell with their toddler? My almost three year old is having a rough time adjusting and that translates to: potty training regression, occasional hitting (only me), general naughty behavior when I’m not 100% paying attention to her. I know it’s because her world is turned upside down but omg give me patience! 😳
