Gradual desensitisation can sometimes help if you feel anxiety in particular settings. If this makes no sense to you, I can give you an example from my life. I had a longstanding anxiety about being anywhere near snakes (because of a horrible movie scene I saw as a child, which traumatised me).
I lived in Germany for a while and did not know at first that pet shops there could legally display and sell live snakes. We rented an apartment right next door to a pet shop. Imagine my shock when I glanced in the window and saw snakes staring back at me. I sped away. Over time, I began to pause as I passed by. Then I began to stand at the window and study them, because the exposure was gradually desensitising my fear and replacing it with interest. The owner came out one day and said I was always welcome to call in and watch him help the snakes shed their skins, or hold one if I wanted to. I did go in and stood right beside them, without a barrier, without anxiety by then, which was pretty astonishing to me. I never felt anxious about snakes again, not even when I suddenly encountered a live wild snake in Texas later on.
