I have had agoraphobia for the past 4 1/2 years. What has helped me may not be available in your area. It is called LENS Neurofeedback. LENS stands for Low Energy Neurofeedback System. It is different from traditional Neurofeedback in that it introduces a low current into your brain rather than just reads your brain waves. LENS is not widely available in all areas. Insurance does not cover it. I had to pay out of pocket. My therapist recommended me to a practitioner who is only in my area 6 months out of the year. Other than that there isn't anywhere for me to get it done. It is supposed to treat depression and anxiety. It is supposed to show benefits in as little as 3 treatments and usually takes a total of 10 treatments. I have already tried TMS Transcranial Magnetic Stimulation with limited success and Spravato nasal inhaler of Ketamine without success. It took at least 6 or 7 treatments for me to notice any improvements. I was only able to get a total of 12 treatments because my practitioner went away. It did not make a dramatic difference in my depression and anxiety, but it did make a pretty significant difference in my agoraphobia. Before treatment I wasn't leaving the house by myself. My Father drove me to treatments. During treatment I started going out to the mailbox by myself. One time I went for a walk outside by myself. Then I started going out to dinner with my boyfriend. Then I went to the movies with my boyfriend. I committed to going out once a week. Monday I drove to the pharmacy by myself. I had my therapist on the phone with me while I drove there, but hung up once I arrived. So I shopped by myself and drove home by myself. So it hasn't completely resolved my agoraphobia, but it has made a very significant difference. The LENS helped with my anticipatory anxiety about going out. It also helped me to stop having really bad days with depression when I had a hard time even just getting out of bed. So in the end I do recommend the treatment. It is not a miracle cure by any stretch of the imagination, but it did make a significant difference for me. Now I just need to keep setting new goals for myself for going out especially alone. I had a total of 12 treatments and I plan to have more when my practitioner returns. It has also helped me so much being on this site and chatting with someone else who has agoraphobia. Being able to share all of this with someone who understands has been amazing because most people just don't understand agoraphobia. Sorry this was so long. I just wanted to share it with you in case it is available to you and in case it could help you in your healing journey. Maybe your results will be even better than mine as it is reported to cure depression and anxiety.
I posted this in a reply to a post on Agoraphobia, but I wanted to share it with everyone as a possible treatment option for Depression and Anxiety too. That is why I made this post.
