My symptoms are tunnel vision, dizziness and light handedness. what am i suffering from?

Panic attack?: When having a panic attack some people complain of tunnel vision with dizziness, lightheadedness, and other symptoms. Along with these symptoms is intense fear or discomfort. The set of symptoms develops abruptly and tends to reach a peak quickly (within 10 minutes), tapering off more slowly thereafter.

Tunnel vision : Tunnel vision can be a sign of a serious problem (such as a pituitary tumor). You need to be evaluated by an eye doctor.
