What is it like being a Medical Office Administrator?

What is it like being a Medical Office Administrator? Is it boring? Because I'm considering becoming one because of my interest in the medical/veterinary field without having to directly having to deal with the patients themselves since I'm not much of a people person. At first, I thought it was an ideal job, but then I started to get ideas in my head like... 'What if I hate it?' or 'What if I find it incredibly boring?' and 'What if I'm not suited for such a job despite the various online career tests stating that I am?'. I'm a bit of a pessimist, and I tend to see the worst side of things, overlooking the good side. I'm good at math and organization, and I like to help people I suppose.

I'm looking more into Vet offices or massage clinics rather than hospitals, but I'd like to keep my options open just in case. I also don't like working under lots of pressure, because I can't concentrate that way, I prefer to do things at my own pace. So I'm asking any Medical Office Administrator, what is it like to be one? Currently, I'm quite nervous in choosing a life career, because I don't really know what I want to do. This makes me even more nervous because of college, which is looming over my head. Another thing are my parents, who are waiting for my decision, and are honestly worried for my future since I can't seem to get set on a certain job. I know I want to work with something having to do with biology and computers without a lot of manual labor.
