Not superstitious. Generally, going to a temple can make people relax and comfort. Old people say that getting a little Buddha nature can ward off evil spirits. Although superstition is also a hint in their hearts, people think that I have Buddhist nature to ward off evil spirits and will be fine.
The most important thing is to relax yourself. Sometimes people scare themselves. If it still doesn't work, go to a psychologist or something and do psychological counseling to see what the reason is. Maybe it's too much work pressure, dealing with patients, or the feeling that life and death are in your own hands. You may be fine at ordinary times, but there is actually an implicit pressure that keeps oppressing you, because after all, the feeling of life and death at your fingertips is still quite great.
