I have the same problem. I have the tendency to be nervous and it always manifests as anxiety. I had been taking .25mg of Klonipin for a few months but decided to stop. It helps with anxiety but it makes me really tired and almost withdrawn.
The main symptom that bothers me is muscle tension. I feel like my neck, traps and pecs are ALWAYS tense/contracted. It has made lifting more difficult. I've tried so many different things. Ortho, neuro, spine specialist, PT, chiro, massage. Not sure if the tension causes anxiety or vice versa.
