I'm actually serious about needing a name. My name for paralyzing anxiety which includes anxiety about being paralyzed is deadlock, but that's ... not a thing that typically eats days or weeks at a time, and often simple deadlock can be broken by meditation and/or THC. There are worse forms of paralysis, what do I call this one.

I'm not sure if this fits, but you might look up "cothymia." it's one of several labels for variants of mixed anxiety and depression.
