Anyone all of a sudden develop constant anxiety? Not even sure if this is anxiety. My body starts shaking whenever I flex a muscle then that body parts starts to shake. I stand up and walk and feel dizzy like I am going to fall over. I wake up several times each night in a cold sweat with my heart racing (every night). I stand up and my heart races. I feel constantly shaking with a painful electrical feeling going down my arms. I am in constant agony. I have had anxiety all my life but this feels entirely different. That painful electrical feeling is the worse. It is like being tortured electrically. Been to so many doctors and as soon as they see I believe I am on klonopin they assume this is all anxiety symptoms. How does one survive living with constant pain and agony. I am not talking the type of feeling one gets if one is afraid of flying or afraid of elevators. I am talking a tormenting I want to jump off a bridge to end the pain feeling. Does this sound like anxiety?
