There are potential solutions but no easy ones I guess.

I think we do this because the need to analyse social situations makes us more attuned to "chewing over old bones". Also we don't have recourse to social re-inforcement from the kind of social exchanges non-autistic people have, so you cannot so readily find solutions. 

It sounds like you have a number of anxieties each interacting to worsen the worry cycles. You could try to get help to resolve any easily remedied worries.

Write down all the issues currently running round in your head. Go through the list and see if any could be resolved simply be asking someone else for advice or just getting medical help for that one thing. If you can reduce the list a llittle it might help.

Also look through the list for common elements. Sometimes worry issues are strangely connected, because anxiety spirals tend to remove themselves several conceptual stages away from the original concern. So there may be one underlying issue for several worry spirals.

You could try to interrupt the worry cycle. Initially this wont be much good, but if you try to do it regularly it will gradually give you longer pauses. Flick your ear lobe, or snap a wide elastic band round your wrist against the more sensitive underside, or just pinch yourself hard. The little pain episode interrupts the train of thought enough to  have to start thinking about it again from further back. In time you may be able to interrupt by just telling yourself to STOP NOW.

You could give yourself some rewards for being able to reduce the anxiety a little while, like a cake or a chocolate.

As classic codger says it is familiar ground for many people on the spectrum. However some of what you describe sounds like serious depression developing - so really you ought to see a doctor. But I appreciate your concerns about doing that - sadly few GPs are either informed, or making any serious effort to be informed, about autism issues, and often you do have to do it on your own.
