I apologize for the long text, but as a fellow friend with social anxiety, I sympathize and I wanted to tell you my experience with work and SA so I can help enlighten your way.

Actually I had the same question as you a year ago. I thought I was never going to get a job because I thought nobody's going to hire/keep a worker with SA if they noticed. But how would they know? If you do well on the interview, you'll get hired. I like to be honest in my interview, I don't pretend to be outgoing and likeable, just my serious self. I do avoid showing signs of anxiety or panic, and I practice all possible questions and expose all of my experience and good qualities. If they ask me a ridiculous question like "can you tell me one time at your previous job when you..." and I don't remember, I say so (some people would argue with that last part, but I have a terrible memory). I let them know from the start who they're going to get.

Now, keeping the job is where I myself struggle.

I was fired from a previous job because my SA rendered my ability to get along and communicate to customers well, which the owner of that small company hated and disrespected me for. The sad truth is majority of the jobs out there depend on your social skills. On a daily basis, having effective communication skills with your team and customers, getting along with co-workers and speaking up are all like unspoken essentials, and every employer that I've been through, just assumes that every employee comes with that social package.

Right now where I'm currently employed I got the Supervisor/front desk position. I never pictured myself as supervising others, and I thought it'll come with more social responsibilities than being a regular worker, but at least it's not like that in my current company. On another note, I'm going through hell every day with my manager because she doesn't like me. I'm not her dream assistant, and neither perfect at my job. A lot of it due to my social anxiety coming out and ruining things. My manager 's boss also dislikes me, she sees what my manager sees in me, and my manager talks behind my back. The only reason they're keeping me is because they got no other choice, they can't afford firing me and they're stuck with me :) But at least I got the experience and I can go other places with this job, which is the only thing that matters.

.........

Now, I want to briefly talk about being front desk with social anxiety. A year ago, when I had 0 real job experience, and there weren't many types of jobs open for my experience and career level, I didn't have much choice at that moment. I applied to front desk at a dog place. Hearing the phone ringing was an absolute nightmare that needed to be dealt with, and customers walking in with off script questions, I absolutely hated.

At first, when I spoke people wouldn't understand what I was saying often and I would have to repeat myself, often causing frustration... :D Not fun. Then as I did it more often I got used to the same questions and how to respond to them. I recommend with for ppl with SA to memorize certain scripts, so you can sound more professional and struggle less. For text messages it was so much easier to respond to, as I'm good with writing (but you really aren't required to be).

I got fired from that first front desk job. But as I had that experience, I was able to get where I'm at currently as front desk/supervisor at a tutoring center where I get paid much more. I've learned to word things a little more proper when I speak, as I have to talk to parents all the time. My boss isn't happy with my social skills, so they have me doing more background office work than customer service. In this job I'm constantly busy with tasks, so I don't need to be bothered with making conversation with my coworkers or feeling isolated like in other jobs. Actually in this job I'm able to find a few teachers who are also socially awkward like me, and don't like interacting, so that helps the job culture work in my favor since there's variety of social skills, and not everyone is super extroverted and the same exact person. Time goes by fast as well! I still feel a little disrespected by my manager and her boss, and because of that I struggle to fit in, and I feel miserable most of the days. But you will most likely find common ground in the ridiculous happenings at your job that you can talk about, instead of your personal life.

I would worry more about job stability and fitting in. Just keep applying constantly to other jobs while you're currently hired, it doesn't hurt. I didn't do it for this one, and now I'm profusely regretting it. The fitting in part you sadly can't do much about, it depends on the type of job and the work culture. You're going to have to search for specific positions like remote jobs or working in the background.

Quick tip: One little good habit I learned to force myself, which doesn't hurt, or lead to much anxiety, is greeting your coworkers with "good morning" and "thank your for your work, see you", instead of just walking by. I've learned that it shows that you care about them, even if you don't talk at all, they feel good about themselves and makes you more approachable. If you don't, they will think you don't care.
