Agoraphobia & Social Anxiety Support Group
Agoraphobia is an anxiety disorder, often precipitated by the fear of having a panic attack in a setting from which there is no easy means of escape. As a result, sufferers of agoraphobia may avoid public and/or unfamiliar places. In severe cases, the sufferer may become confined to their home, experiencing difficulty traveling from this "safe place."

I feel all alone in a big box, in a strange "not my home" location. The smells and sounds are different and it takes a while to settle down into that atmosphere.
I have personally reached out to the following prayer line many times. They don't try to change your religious viewpoint but listen and pray with and comfort one. It is Christian so forgive me if this doesn't fit for you. The unity website has a lot of written resources, too.

What about listening to something like a podcast or recorded radio shows? I like to listen to coast to coast am on the app (costs a little bit of money) when I am feeling overly sad, lonely, too tired to sleep, or just want my mind to shut down. Because the radio shows are unusual topics which engages my brain. Some people like audio books. There is also the Calm app which might be helpful if you can just listen but not actually talk to relax your mind. Again, if you need to be talking then this suggestion might not be helpful. But I feel less alone when I am listening deeply to something so I mention it. My relative swears by something called "Whole Tones" which is tonal music that changes the brain waves.
