please I'm desperate I need help

I have a 5 year old who is just being awful it's every night with him. He doesn't want to listen, he yells, he screams, he kicks and hits things, he's smacked me a few times, he throws things... I just don't know what to do I've literally tried everything. I feel like I'm losing my son. We used to be so close and lately idk all we have anymore is bad days and it's breaking my heart. My husband and I are at our wits end...😩😩😩😩💔💔💔💔 please some advice.. I feel so hopeless right about now
It all starts with the littlest of things too..
