Trending @Accenture; Feeling Lost and Overwhelmed in a New Role

I’ve been feeling lost since I joined Accenture four months ago. It's a new company and a new domain, and I feel like I'm not doing enough. Initially, things seemed manageable, but I struggled. Now, when I look back, it seems like it should have been easy, and I feel like I was the only one too slow or too "dumb" to pick it up.

They've now assigned me another task for requirement gathering, but I don’t completely understand it, especially the technical parts they're discussing. The Product Owner keeps saying it's not their duty to guide me, and that makes me even more anxious. Even though I have eight years of experience, I constantly feel scared and have lost all my confidence. I spoke to my manager, but nothing has come out of it. I feel like I’m the only one who can’t seem to grasp things, and I'm worried about how this is affecting my mental health. What should I do?
