You have an anxiety disorder (that may or may not have been underlying) which is being instigated by drug use. Stop using drugs, excercise, eat well, allow the chemicals in your brain to recalibrate.
In the unlikely situation that these symptoms continue, I would look into finding supplements that can help with your anxiety, and in the worst case, medication.
Nothing is in your mind, the psychological bearings induced by our drug use have a strict relationship with the physiological bearings. If your mind is in a good state, you can guarantee your body will be too.
Good luck
