Anxious about my first day tomorrow

Hi all. I have been WFH for the last few years, doing what is basically specialized data entry – boring, low pay, but extremely low stress (I was one of dozens of workers doing the same thing, no video meetings, just me and my laptop). Tomorrow, I start a new WFH job with more responsibilities, and I’m getting really nervous. The work should be fine, it’s something I have done before, but never remotely. My new bosses are in a different state, but I am the only employee doing the job and I’m worried about how often they will want to video chat, what happens if I have tech issues (my previous job had an IT department that could remote into my laptop and fix stuff without involving my bosses, this new job is with a small company with no IT department), and how to impress/get to know my bosses when I will likely never meet them in person. I’m just anxious about all of the extraneous stuff that comes with a “real” job and how to do that stuff remotely. Any tips (or encouragement) would be greatly appreciated!
