adult autism/adhd/diagnostic exam test?

hello where can an adult get testing for autism/adhd? edit: interested in any other learning disorder/neuro atypical/ IQ test/etc. I was supposed to be tested as a child but because my parents didn't want me to be labeled I wasn't. I'm an adult female that struggles to even feel human, I even struggle feeling like a "woman" and have thought about transitioning to a man at times. a lot of my trans friends were also autistic and encouraged me to get tested. i have seen a shrink and she said i had PTSD and was a "highly sensitive person" I honestly suspect autism. I'm in houston but willing to travel anywhere. I see some of them priced up to the thousands and wanted to go somewhere legit and ofc LGBT friendly. Don't suggest Legacy I have been on their waitlist for years LOL
