I do hope they rework some of these traits as well as the rain. In real life rain doesn't cause sickness and in game it does. In real life Claustrophobia is being in an extremely enclosed place like a closet, not a house. Also, doesn't panic eventually get you killed on it's own? I went to sleep in a house as a character with claustrophobia and ended up with a fever. By immediately running outside and quickly running into houses and eating food, I eventually outlasted it by minimizing my time indoors. Either way it's a bit strange how it works and I hope in the future it's all explained a bit better.
