What works best for me is to never do anything differently just because of the anxiety. When I do certain things just because of my anxiety, the number of triggers increase and my world becomes even smaller and scarier. I notice that if I continue to do things as if I don't have anxiety, things get better and the less scared I am of the situation / trigger.

I remember one time, I went out of the house because I had a panic attack inside my room. Then, even the thought of being inside my room scared me. When I was about to go back home, the walk to our apartment was so frightening. It was as if my house turned into a monster or something. Running away made the link stronger. My primitive brain was thinking, "Why are you running away? That means your house is dangerous. I must give you all the fear signals next time you enter the house." Hence, it became a self-fulfilling prophecy.

The next time it happened, I just accepted the fear, even if it felt so real, and tried to continue with what I was doing. It was a long battle but eventually, I wasn't scared anymore and the link between fear and my room disappeared.
