Is this ongoing or something that just developed?

I moved to a new area and it is out in the country and very open, and it caused me to have a lot of anxiety every time I got in my truck.

Then my truck broke down and for a few weeks I have had to take buses. I don't know why but the bus makes me feel really protected and it has reduced my anxiety about all the open space.

Suggestion: change things. Like use bubble bath soap (or I use shampoo) and fill the bathtub up with hot water and let the water really warm up the room and the tub. Try soaking in the tub. You don't have to wash, just let the sudsy water do it for you. You could use candlelight. Sometimes I take a hot bath in complete darkness and I love it as I feel like I am like a baby in the womb. I have also known of others who got over shower phobia by showering in darkness.
