Dear New Member~
I'd like to welcome you here to the Forum. It is a place where if you look around you will find many who react to loud noises, a noisy environment or to feeling anxious or frustrated.
One most significant point is everyone is different, and reacts to different things in different ways. If I'm anxious I get a headache, if I'm in a noisy environment I wear earphones to cut it our. I ground myslef wiht a mindfulness app that stops me thinking about the current problem and become calm.
Other people react to different things and have different way of dealing wiht them.
I'm not sure how significant you childhood test was, autism and neurdivergency are scales, not on/off diagnoses, in fact neurodivergency is held by many not to be an illness but simply a different way of looking at and reacting to the world.
In your case probably scratching your palms may perfom the same function as my mindfulness app. At the time I certainly do not want to talk to others.
Having a label my seem important to explain what you expereince, however that does not mean it does anything to help. It is more important you take steps to cope with the things in the world you react badly too. Earmuffs or plugs for noisy environments may help, knowing you are becoming anxious may mean taking a break and doing something soothing, the same wiht frustration.
These are coping skills, and the more you use htem the more experience wiht htem you have and the more effective they will be.
As matters involving the head can be by a large number of causes I would strongly recommend you see your GP and be tested for any physical problems that my be cause your reactions or making them worse. I had cat scans and an MRI before it was decided there was no physical cause.
If you would like to talk some more that would be welcome
