Sadly, unemployment among autistic individuals is really high (vaguely remember a 80% statistic)... Though, specific fields can have extremely high prevelence of autistic people (again vaguely remember a statistic about 20% of software engineers being autistic).
We are living in a world where our needs are ignored (if not mocked) and our super valuable skills are underutilized... You should remember that you can only control your behavior, it's not entirely your fault you cannot find a job. We are not broken, the world is.
I know you are not looking for tips, but I am going to give you one anyway... Make your special interests your career. Not only will you get to spend much more time on them, you will also find more people to share your passion. Additionally, the time and effort you have spent in them will make you a high value hire.
