I suffer from agoraphobia, have you heard of this?
Yes! It is an anxiety disorder. I am so sorry to hear it. 
Do you have any problems like those of agorophobia?
I actually do. I suffer from recurrent unexpected panic attacks. How long have you suffered with  agorophobia?
I developed it after having one or more panic attacks, causing me to worry about having another attack and avoid the places where it may happen again.
I know Agoraphobia is can be due to a combination of genetic and environmental factors. Do you know where yours came form?
