welcome to Healthcare Magic.
Your symptoms are very short duration (1 week) to make diagnosis of anxiety
disorder, although it is one of the possibility in your case. As, symptoms are sudden onset, there is need to rule out other problem in following hierarchy:
leading to dizziness
and vision disturbance
-Ophthalmic pathology leading to tunnel vision
-Anxiety disorder or panic attack
If there is no problem after examination by general physician and ophthalmologist, you can visit to psychiatrist
to rule out anxiety and panic attacks.
Wish you all the best.
