There was a job going for a receptionist at my dd’s school which would have suited me perfectly but I didn’t apply because of speaking to parents and answering phones.
Okay, so it wouldn't have suited you at all then, would it? You just liked the idea because it sounded convenient and easy.
There are jobs that will suit everyone perfectly. It's just a case of identifying them. That's the first hurdle. Besides which, few people are lucky enough to be in the perfect job yet they get on and do the job they have nonetheless. I think too many people expect that their job should meet all of their personality needs and dreams and be enjoyable, enriching and rewarding to do, which is not really the point of work. That's why it's called 'work' and why we need to be paid to do it. If you do get any enrichment or sense of purpose from your job, then that's a bonus but it's not a pre-requisite that most people can afford to hang around and wait for.
Obviously there is little point in applying for jobs you know you will be completely crap at, but holding out for something to be just right that will not challenge you in any way is entitled and unrealistic. You could work in a supermarket presumably, as there is very little need to interact with strangers beyond saying hello and asking if they have a Tesco clubcard. Other than that, it's not highly stressful or especially over-stimulating. Repetitive factory production line work is not over stimulating either. It's dull and probably tiring, maybe noisy, but you might be able to wear headphones. Delivery driving is ideal for people who don't want to speak to people much. There are some time pressures involved, but you can't have everything.
There are jobs you can do that are entirely work from home and admin based, no real need to interact with anyone in person or on the phone. Admittedly they are in high demand as you can imagine, as no fucker these days wants to get dressed, leave the house or have to meet anyone or speak to anyone, either on the phone or in person. So you'll have some competition, mainly from everybody under 25 (who incidentally will also believe they are probably austistic and/or ADHD and say they are highly anxious and phone phobic) but those jobs do exist.
