I might have Aspergers/high functioning autism, but I have some doubts. Better worded: I may end up getting diagnoses if I went through with a diagnosis, based on the comments of my psychologist.

I read your post but I don't really know what kind of feedback you want. We cannot judge you.

Also, it is not called a mental illness for a reason, as people are not ill, but different. Especially so with Asperger's vs pure autism.

Furthermore, it is just a label. I am not sure it means much. People are people, they are all different, and no one can be sure what kind of processes are going on, and going wrong, in your brain. Different people with different, and similar, quirks or traits, will get lumped under a label. They are still the same person.
Labels are based on symptoms. Causes are completely unknown and therefore unknown. One person with the label may have it because of genetics. Another one because of experiences. One may grow out of it. Another may not.

I also disagree that when you have the label, you can see if others have it or not. If you are truly autistic, you may not even notice you are different, as having insights into emotions and feelings from someone's else's perspective is exactly what people with autism are supposed to be bad at.

And even for 'normal people', I am not sure if they can do it.

Like I hinted at earlier, only psychiatrists make diagnosis. And what quality and value they have seems not completely, but quite, arbitrary to me.
