Agoraphobia is really hard thing to deal with, I have this anxiety disorder and I am not very happy about it.
I am very sorry to hear that.  I have a friend who has an anxiety disorder and he struggles with it as well.
Iam sorry, I know what hi is dealing with. Open spaces, public transit, or simply being outside their home is very hard for me.
Yes he will on occasion get panic attacks and he does not like to go out much.  Lately he has been better after some different medicines.
It is uncommon for agoraphobia to resolve without treatment. Treatment is typically with a type of counselling called cognitive behavioral therapy.
I believe that is also used to treat depression.  Are you doing this therapy yourself?
Yes and it is helpful. The condition often begins in early adulthood and becomes less common in old age, so I hope that will stop at some point.
I am very glad and I hope that it goes away for you.  Agoraphobia will not likely resolve on its own, so I am glad you getting help!
