Absolutely. When I'm feeling particularly anxious, sudden noises or prolonged sounds are hard to take. Noises that would hardly be noticed in normal times.
I see that your primary is agoraphobia. I have more than a touch of that but it definitely isn't my primary. I feel almost as much anxiety in my bedroom sometimes.
If you don't mind me asking...does your anxiety level get a lot better when you're inside or just a little more bearable? I can understand that you must sometimes feel like a prisoner even if the anxiety level is much lower when you're safe inside.
