I am at my wits end with my childs tantrums: Advice?

I have an 18-month-old son who is so badly behaved! He screams all day long! He throws a fit about literally everything, even stuff he knows he can’t do/have like touching the stove, I tell him no, and he screams and throws himself on the floor, and the tantrum lasts until he tries to get into the next thing he knows he can’t, then it starts over again! He hates car rides; he hates sleeping, up multiple times a night, and up around 5 am every morning. He hates when I try to leave him with someone for a bit some and his older brother (5) and husband can do something. He’s so bad they always call and ask us to come to pick him up. He absolutely won’t play with any toys, even if I sit on the floor and play with him. I literally am losing my mind and want to rip my hair out. It’s getting so bad that I really don’t want to be around him. Work is my escape from him, and on my days off, I take him to daycare. Does anyone have a child that is/was similar?. Will it get better? Or is this a preview of what he will be like his whole life?!

Its not a preview of what he will be his whole life. When you have multiple children you will find that this is common at this age. I had two out of my four that were really bad with tantrums. I think that communication or lack thereof is one of the causes. They struggle so much trying to be understood. Just do the best you can and don’t give in to the behavior. In time he will out grow it.
