Doctor basically said I can't be autistic because I'm studying psychology

I had a meeting with a psychiatrist yesterday and I brought up that I may be on the autism spectrum. I started reading the signs I've noticed in myself off a list on my phone, and the whole time he was pretty much just looking at his computer screen scrolling through my patient files. When I was done, he just took a deep breath and said: "Aren't most of those just things that appear in the normal population?"

I immediately got a little irritated because of this "everyone's on the spectrum" rhetoric which I've heard one too many times in my life. I proceeded to ask him what about me exactly gives off the impression that I am NOT on the spectrum. His answer was, and I shit you not...

"Just the fact that you've gotten in to study psychology tells me that you have adequate mental and executive capabilities"

For context... In my country, getting into school to study psychology is indeed difficult, because there's many applicants and you need pretty good grades to get in. Me being the social recluse I am, and having had a special interest in psychology since I was 12, had nothing better to do in high school than to study. That's why I got in.

In university, I've had struggles with my studies. I'm a social outcast and struggle to keep up with the pace. Going to university is so overwhelming I do most of my studying from home. None of this matters apparently, because at some point I got into school. He also questioned me on why I want a diagnosis: the answer being that I want peace of mind knowing I'm not a weird alien that somehow got teleported to Earth, but just autistic.

I hate being a woman. I just hate it. If I was a man I would've already gotten diagnosed. Maybe if I wasn't so independent, I could get diagnosed. Maybe if I'd never learned to mask, I could get diagnosed.
