Ultramarina, a couple of thoughts coming from where I am (DS9 has AS).

I really trust cognitive behavior therapy for working on anxiety. It is great for smart, verbal people-- they learn how to reason their way out of their anxiety in a way that is meaningful for them.

My preference is also to have as much information as possible-- anxiety that comes from Asperger's (because you can't quite figure out other people) is different from the kind that comes from ADHD (because you can't quite trust yourself to do the right thing). If you can get to a neuropsych (it'd have to be just the right one, with particular expertise) they may be able to confirm a source for the anxiety, and with that give you a path forward on how to treat it.

Best,
DeeDee
