Please tell me this gets better 😭

I love my kids so much but 3 years old is no joke. They flat out do not listen because “me no want to.” They physically fight with each other and screech so loud. They’re all over the place to the point where I can’t even think a complete thought without being interrupted. I have a headache most of the day. They ask “why?” about everything. And it continues. I’m so.worn.out.
