While for now, you can't get what you want a professional diagnosis settling for "I suspect I am autistic" and making decisions on the assumption that you are autistic might get you what you need.
I have been on this site since 2013 and have read about a lot of reactions of loved ones to a diagnosis. What I am saying is that there is no guarantee your family will accept a professional diagnosis.
Acceptance from our families is important, there is no minimizing that. But you are 39 years old. Being an adult sometimes means prioritizing your own needs ahead of ahead acceptance from your family.
The adult diagnosis situation is bad but noticeably better than it was when I started here. I see no reason why that won't continue so eventually I think you will get your assessment. We are only here on this earth for a limited amount of time so it is a good idea to make the best of bad situations.
I would advise taking a break from trying to get assessed for 6 months or a year or so. Live your life, enjoy your interests etc. Your mind will be in a better place and thus possibly able to pursue more effective strategies to get an assessment.
I hope some of this is helpful,
Good Luck,
