This is something that varies from country to country, and each person has a completely different experience with it. Here, there is still very little autism awareness and a lot of social taboo concerning autism and mental health issues, so many people who have problems don't seek help and are undiagnosed. Adult ASD diagnoses are almost unheard of and I'm sure that there are a lot of undiagnosed adults around, with various issues, backgrounds, life stories and mental health issues.
Here, the doctors and psychiatrists just ask you what your problem is, then prescribe you medication - they don't offer therapy, I believe one has to go to a psychologist for that.
Unfortunately, mental health is an industry with big bucks behind it - they charge extortionate amounts for their drugs, discourage the use of natural remedies or any remedy that can't be patented by them and a profit made out of it, the doctors are their puppet and they pull the strings. Drugs are commodities to be consumed, and patients are the consumers. It's dehumanizing.
In this country, there was a huge scandal about politicians accepting bribes to allow the pharma companies to basically charge what they like, extortionate amounts for drugs like cancer drugs, wherever there is big money there is also big corruption.
