Diagnostic Assessment

Hi all, I have my autism diagnositic assessment next month and it is causing me alot of apprehension and anxiety.

I am 32 female and like many will be late diagnosed, I have a lot of bad experiences with metal health professionals where I have frequently been misdiagnosed or not listened too, or simply told medication will fix it all.

I am due to previous experiences worried I will again have a bad experience not receive a diagnosis and essentially feel like I fail at life due to all the struggles I have being autistic. 

Did anyone else in a similar situation have the same concerns? How was your experience? 

I am also aware the assessment can be quite draining so any advice on what to expect would be great

Thank you
