I am tired with my 18 months tantrum/meltdown

Hello mummies. I am really tired with my child’s tantrum. She is only 18 months. She is recovering from fever. Yesterday, she woke up at 430am and we gave her milk. But she cried feeling very angry non stop. It got me soooo angry! Why am I feeling irritated and angry? It’s like I’m the one who tc of her but she finds for “papa papa papa papa” but her papa wasn’t all the time there for her. Any tips to give this mama to calm down? I’m feeling stressed tired irritated angry. I do not want my child to be astray from me when I have this feelings. And, I do not have emotional support. Not from my own family. In laws or husband.
