I do not know you, your parents or your ages but to generalize it is likely when they grew up knowledge of autism was much more limited then today. If they grew up before 1988 they grew up at a time when for the most part only "severe" cases were diagnosed and even most of these cases were misdiagnosed. Even after 1988 public knowledge was limited to the "Rain man" stereotype. But that was then this is now, so the question is why were they not up to date enough to get you help? They were busy with the day to day job of working and raising a family. Autism has been in the news a lot lately but so has a lot of other conditions. We are in an era of continual media panics about diseases Zika this year, Elboa last year etc it becomes easy to be overwhemed and tune it all out.
I did not get diagnosed until age 55 and a lot of mistakes were made by me, my parents, my educators, my employers due to lack of knowledge. In my parents case they did the best they could working with absolutely no knowledge of what was going on with me. How can I be angry at them?
