Hi there ~ Relaxation may help with anxiety
. There are different forms of relaxation and assuming you are well aware of those and have been using those strategies to overcome your anxiety problems, and they are not helping, I would suggest that you consult a doctor. A pulmonologist would be the person to go to, to have your breathing problems addressed. The twitches though seem to be a tic disorder
, exacerbated with anxiety. Hope this helps. Take care.
