Arthur Theophilus S. Butterworth, A phrase often used regarding Autistics is:
<=>"If you've met one Autistic you've met one Autistic."++
In other words, we're all different, and if you are Autistic you'll be just as much a unique person as the rest of us are.
Note that your parents might not know much about Autism. Until 2019, when I was 64, I knew virtually nothing about it and would've dismissed any suggestion that I might be Autistic. For folk who haven't read up on the topic (such as me, before 2019) the term "Autistic" brings up a stereotype of someone with very severe symptoms. I was surprised when I first started reading about Autism and realized it described me.
And, I'll offer an idea here that is likely to cause some negative reactions on WP. If your symptoms are mild enough and you are not seeking formal accommodations then I see no reason for you to rush into a formal diagnosis. With or without a diagnosis you'll still be your weird self but without the label people will have to take you as you are rather than leaping quickly to the stereotypes. With or without a diagnosis, if you are sure you are Autistic you can learn about Autism...that is learn about your own strengths and weaknesses and develop techniques for working around them. Personally, I'm glad I was able to build good academic and professional credentials before I was diagnosed. Having that label before I'd built some credentials might've closed some opportunities for me, as happened to this young man! (I wouldn't have chosen to wait until my 60s to get the diagnosis, however. A two or three decades sooner would've been nice!)
If you need accommodations or medical care, however, you need a formal diagnosis.
Good luck!
