Does it matter why? Trying to figure that out can just increase the anxiety. Try sitting with the anxiety instead and try to give your brain a rest.

It works better for me then trying to identify why I am anxious or depressed or cognitively confused. It is what it is and all you can really do in the midst of it is to acknowledge how you are feeling and counter it with a coping mechanism, like breathing and reviewing the T suggestions.

Is there any chance you can call your pdoc tomorrow so you don't have to wait out the weekend with things going as they are right now?
