Help please

My oldest just turned 3 and is absolutely horrid to handle I know it sounds mean but the actions he does is just awful and draining he screams like he’s being hurt just because it’s bedtime or doesn’t get his way. I’m at my ends and I’m tears because I don’t know what to do anymore the fighting with him and with my husband about his behavior and not listening at all to anything. Please any moms out there that can help me
