How do you discipline a 2 year old?

Guys I’m at my wits end lately. My son just hits and screams and kicks and I’m losing my mind. Yelling doesn’t work, time outs don’t work, getting in his level and talking to him doesn’t work, redirection doesn’t work. NOTHING works. I’m tired. I’m emotional. I’m exhausted. What do you guys do that works? I’m losing my mind.
