The best forms of therapy available for agoraphobia include cognitive behavioral therapy (CBT) and exposure therapy.
Cognitive behavioral therapy (CBT) is a form of talk therapy or psychotherapy. It helps to deepen an understanding of where various behaviors come from and what triggers them. CBT, in particular, will teach you to identify distorted or unrealistic thoughts and come up with ways to cope when your agoraphobia strikes.
Exposure therapy will expose you slowly and safely to situations or places that trigger you, so your fear begins to diminish over time.
These types of therapy can be used on their own or in conjunction with anxiety medication to treat agoraphobia.
