In over your head
If you are “in over your head,” it means you are in a situation that is too difficult, too complicated, or too much for you to handle.
Examples:
1- I agreed to help my friend build a website... but I don’t even know how to code. I’m definitely in over my head.
2- A reality star tried to run for office and quickly realized politics was more complicated than it looked. Many said he was in over his head.
