As a child I was diagnosed as having asperger's syndrome. I always suspected that it might not be true. Because I was completely normal until the age of 6 or 7. And have progressively gotten better since I was 18. Now I'm 30 and unless I'm having a really bad episode I'm hardly different than anyone else. 

I can definitely see how doctors would have thought I had asperger's though, because as a child I was disassociated pretty much all the time. And the symptoms of  asperger's and disassociation and can look vary similar. 

I also think my mom may have influenced the doctors on my diagnosis. She is extremely manipulative. And has always expressed the desire for her children to live with her forever and never become fully independent. So if doctors proposed  to her that I might have asperger's, a disability that often perverts people from living independently, I'm sure she would have fed them as much information as possible to confirm it. While leaving out any information that might get me diagnosed with a mental illness that is largely curable.
