New Work. Feeling utterly confused.

Hi, guys. I just switched to a new role (UX Writing) and its been 14-15 days. I am getting major work FOMO here. Here are two things I am feeling, help me navigate through this?

1. I am not aligned to a project/account yet. Feeling a bit restless, I feel like reaching out to seniors and teammates and I do. Yet, there’s little clarity on how I will be resourceful to the entire set up.

2. Brushing up on my skills until formal tasks are allocated to me. However, I learn more on the job, rather than through training. How to make most of the time and resources available?

3. I am not sure if I am overthinking this, but I feel like my role isn’t as well-etched as I first thought it would be.
