When will this phase end😭

My daughter turned 3 in February. I thought 2 was rough but when 3 hit, OH BOY😂

I thought the tantrums and attitude was getting better but it’s only gotten worse it seems. I can never do anything right. She’ll ask you to do something one way then scream like you did it wrong. Everything, and I mean everything, is a screaming fit.

She’s recently started to try hitting me and others when she never did that before. I’ve tried ever form of discipline and she DOES NOT CARE. At all. It only fuels her to freak out more.

I’ve been trying to get her to breath to calm herself down and sometimes she will but most times not. She just ignores me and keeps screaming. She won’t eat anything but junk. Bedtime is a fight. Brushing teeth, bathtime, getting in the car, putting shoes on, getting dressed, EVERYTHING is a fit. I feel like I’m at my breaking point. WHEN WILL THIS END??

She’s also gone from sleeping great 10-12 hours at night to now waking up constantly and taking sometimes hours to go back to bed. 😭 and I also have a 8 month old who is also up All night from teething 😭😭😭😭😭 any help is appreciated
