I have been suffering from anxiety from many years.I have breathing problem and fear problem.I did my ecg and echo cardio,and it became normal.The fear comes in a particular time mostly.But sometimes I become normal..I am a law student..If I talk more verbally then I become tired.i have a little bit of low blood pressure..I don't know why it is happening.Now I am taking homoeopathic medicine.Will it work? After ecg and echo the doctor prescribed some medicines for fear.I didn't take those..If I hear sudden death of someone I become very anxious, it seems that I would fall down on the ground, this the main problem.
