Hi Dona
I think you really should go to see a doctor, they will help you with medication. I remember myself, and how i suffered with this for months, thinking and hoping it would just pass on its own and i didnt bother going to a doc. In itself that made my agrophobia and panic worse because i didnt know what was happening, how to self control some of the symptoms like breathing properly,(which is where the dizzyness is caused) and in the end got into a right old mess, simply because i didnt get proper help. you could also be suffering from deppression, which is important to get treated just by itself. Try to force yourself to go, it's really worth it and it will make you manage your symptoms much better.
Best wishes
