My mom doesn’t believe that I have f84.5 and says that I’m just a wimpy lazy ass

Well, the main issue is stated is above. (I’m sorry if there’s any mistakes in text I’m not native English speaker) The problem is that I always had this headache, I just never knew why. The point is I always ignored it, (I’m 16 now, and I felt it since when I was 7 because of hypersensitive stuff stimulation). I only left school when it was getting too hard. School doctor never knew why because my blood pressure never had any issues. Finally, after 9 years I decided to check why. After a few weeks of researching, I came to conclusion that I have Asperger’s and yeah I had some symptoms since my very childhood (I used to play with the same one toy everyday 6-7 hours daily, then I started reading too early and too much for my age, first time multiplied numbers at age of 5, and about reading: I read Harry Potter 5th tome in a single day at age of 7. Well, that’s not the main point though. Just was proving that I wasn’t overthinking stuff. Back to the point: I need some advice what to do, I’m trying to tell her and she just says that I’m being wimpy and my headache caused by hypersensitive stuff stimulation is just caused by me using my mobile and pc too much. I don’t know what to do or say, no matter how hard I try I can’t convince her. I can add my whole “medical history” gathered by myself if it’s needed
