1, comfort yourself
The world is amazing, and there are many creatures that we have never heard of or seen. In most cases, we can't avoid these creatures, so when we see the spider we are afraid of, we can comfort ourselves, "It's just a spider, that's all." In addition, these non-aggressive creatures will not bother you if you don't bother them. Comfort yourself more, and your mentality will change slowly. If you want to scare yourself more, it will only make things worse, such as suspecting that you have psychological problems.
2. Change your mind.
When you meet a creature you don't like and are afraid of, you can look at it as a bystander. Maybe through your observation, you will find that they also have their loveliness. Try to make your heart strong, at least you won't be scared when you see them.
There is a special situation. If you were bitten by a spider as a child, you will have a psychological shadow, and this shadow is hard to forget. If the situation is serious, it is recommended to see a psychologist to solve the problem fundamentally and avoid aggravating the problem.
