Assessment time

Hi Wave 

New to the community. My gp recommended this site. I have an assesment for Adhd next week but am also waiting for autism assessment.  My gp said it's about  a 2year wait ..I'm a year into the wait ...just woundered how accurate this was. Does it vary from area to area? If I has known I could do autism along with my adhd on rtc I would have but only just found out I could of done both together.
