I have not been diagnosed with agoraphobia, but my biologica

I have not been diagnosed with agoraphobia, but my biological mother was. Is this hereditary. I do enjoy staying indoors more than going anywhere.

Welcome to Support Groups, As far as I understand, it is a learned behavior just like any other phobia....
The good news is that it doesn't "have to happen" and if someone does have agoraphobia, it can be overcome with the right changes..
If someone likes being at home but isn't scared of leaving, I consider that being a homebody.
