salam doctars and members

since two months i was suffering from stress and fear so i developed anxiety symptoms such as fast heart beat, feeling heavy headed/light headed, and feeling buzzing,vibrating and tingling skin sensation. i also went to doctar and he said that is anxiety and its gone take time to recover. he also did blood tests like FBC, BONE, UREA, thyriod and liver tests al lcame back normal. Now my question is that i don't stress anymore, but still get the anxiety symptoms. Other symptoms are ok now but i still get buzzing and tingling in my hands and feets. i want to know that how long does it take for anxiety symptoms to disappear. coz some time i get scared what if its any other disease coz im not stressing no more.  

  thanks
