In Germany? :o
As a diagnosed German I can tell you not much changes, there’s virtually no therapy for adult autistics. I understand why your doc said that.
Though there was one large benefit for me and it’s that after we applied for disability the Arbeitsamt got much more lenient with me and was actually useful in helping me find a job.
In the end, if you can’t let go, seek the diagnosis, if not, take from autistic communities whatever little tricks help you, discard what doesn’t and call it a day. Much less trouble :)
My logic was always, if == is equal, then for >= we replace one of the equal signs to denote that it doesn’t have only be equal but can be both.
But that was probably also influenced by languages where == means the value is equal and === means value and type have to be equal for the comparison to be true. If you compare “5” and 5 in those languages, == will be true and === will be false, since one is a string and one is a number.
At the end of the day, those signs are arbitrary conventions. People agree on them meaning something in a specific context, and the same thing can mean different things in different contexts. A in English represents a different sound than A in Spanish, and sometimes even in other dialects of English. Thinking of out like that helped me to keep the conventions of different programming languages apart.
