Just completely lost all motivation - is this work?

Has anyone lost their complete motivation for anything? I’ve always been a very high achiever type a type of person. Got a great job after college and am trying to navigate the world post grad.

Just started a new role and I’m completely overwhelmed. It’s definitely not what I was expecting it to be in the workload is a lot greater than expected. I’m wondering if it’s a industry thing or if I need to just figure out a way to stay motivated. I’m also in my 20s FYI.
