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.
