[ Special Education ] Open Question : ....do i have autism? have my parents bin lying to me?

I'm 12 years old and i feel like my parents are lying to me......I don't think that i have serious autism maybe just mild autism but it feels like my parents are lying to me cause lots of my friends sometimes treat me like a child and say sometimes "aren't you autistic?" like maybe my parents told there parents that i was autistic and then they told there kids thats? Why would they lie...?
