How to deal with dad

I (15 NB) am probably autistic, and in waiting for a proper diagnosis. My dad last week said, since I am supposed to enter professional field in 6 years, that he wants me to be more "autonomous".

He is scared because I don't integrate social cues well, and that I do not socialize as often as others do. He said that people came to him saying "Is your daughter autistic" (not in a good way) because of my noise cancelling headset, and that "in professional field, you will not have accomodations".

He does not want me to have to integrate social cues only at 40 like he has done, and want me to be less weird because "If you are too weird, no one will want you on professional or social fields". He also expects me to take my headset off because he thinks that it made noises that I could support before unsufferable. I also do not express myself very well, and that i am unable to handle stress, and he wants to change that. He stated that he will put more pressure on me, and I am scared, since it's very difficult for me recently to handle self and school stress. How I can do to change that ? How do I make my dad understand ?

Note : My parents are separated, and I live 1 week with my dad and the other with my mom.
