thanks for using health care magic.
I have gone through your available history.
Dizziness, blurring of vision can be a symptoms of anxiety. but you must rule out physical causes of panic anxiety like diabetes, thyroid dysfunction
or vitamin B12 deficiency
Panic attack may occur without associated depression.
If your physical examination including blood test for sugar, thyroid and vitamin b12 comes to normal, than it is more likely because of anxiety.
In addition to anti depressant
drugs, you can also go for relaxation exercise and breathing exercise
avoid caffeine in excess.
