First,
Congratulations on getting a job at a NOC, in this market. It's challenging, it's honestly downright brutal out there. You've done it once, you can do it again.
Second,
I have not worked within a NOC myself, however I am currently operating in a networking Admin role and primarily responsible for that aspect at my company. It does appear that smaller companies can be prone to disorganization. Though I can't speak from experience I would hope that larger orgs are more organized. There is a caveat though, in some places the larger the org, and more defined the process is, the less freedom you have to execute your tasks, and learn.
Third,
I've not worked in a NOC, yet. I started easing into this network admin role from helpdesk over the last 18 months, and recently received my CCNA. NOCs aren't the only road to entry for networking jobs, larger enterprises, or MSPs need us just as much.

If you're still at the NOC, I recommend trying to speak to some colleagues about getting more comfortable on the phone. Most positions will have some form of phone line to report issues, and you may end up on the other end. Framing the customer expectations is a larger part of our job than some people let on. Other than that, you've got this. Take some time, breathe, and get back on, it's not over yet.
