OK that list is compatible with a possible diagnosis so IMO it's worth seeking confirmation.
I just want to address this comment :
You're not the first person to say something like this here. You should know that the chances of that having happened are infinitesimally small. The Autism Spectrum that we know of now wasn't even introduced as a possibility until 1981, and wasn't included in the diagnostic manuals (DSM & ICD) until the mid 90s. Prior to then, the only formally recognised autism diagnosis was "Childhood Autism Syndrome" (aka Kanner type autism) which required you be almost or completely non-verbal and have Intellectual Disabilities - what many people mistakenly refer to as "severe autism" these days.
Almost every diagnosis of verbal, functional autistic people without Intellectual Disability has occurred in the last 25 years - it's one of the main drivers behind the false "epidemic" narrative.
I was diagnosed in the 80s by a psychologist who was WAY ahead of his time and nobody knew what to do about it after he gave his verdict. They just carried on treating me like a naughty, lazy, uncooperative, obdurate child. I was threatened with borstal, despite never having committed a crime, just for being a difficult pupil who "refuses to meet [his] potential."
I have spoken to dozens of academics and doctors about people diagnosed as far back as myself and only two have ever come across someone with an "Asperger type" diagnosis such as mine from before the ICD/DSM incorporation. The highest estimate any have come up with for the number of people diagnosed before the mid 90s was "Maybe 10,000, at a push, and all of them children at the time".
So to put your mind at rest @SixTimesNine there is no chance whatsoever you had an autism diagnosis in the 1970s providing you were verbal and not Intellectually Disabled. The chances of you receiving it between 1981 and 1994 are so incredibly low it's not worth the time to investigate. Your list does have a number of pointers towards you possibly being on the spectrum, so seeking clarification is a good call, but don't dwell on the past - look forward to the future and meeting other people who've shared your struggles

I tried asking my elementary school if I had a diagnosis (back in the 1970s), but the records were destroyed because of time limits
