I was agoraphobic for the last 4 years of my drinking. It took me about 2 years sober to fully recover. At the time I got sober medication wasn't the go to remedy, and I'm grateful for that. Had I been medicated that would have merely treated the symptoms. I was interested in healing, and getting to the cause.

Diet had a lot to do with my anxiety and panic. Sugar (and flour) being the number one offender... alcohol, while I was still drinking. I'm learning that many other things also contribute to anxiety and depression including vitamin D levels, amount of omega 3s in our diet, water (I was living in a constant state of dehydration for years) topping the list. What we feed our bodies contributes much more to our mental health than most people think or want to believe.

One of the most important things I had to learn to do however in order to overcome the agoraphobia, was to become unafraid of the panic. I know, easier said than done. I had to first realize I wasn't going to die or go insane, and then learn to walk through both the attacks, and the things that set them off. Prayer helped a lot, as did consciously getting 1 extra thought into my brain when the panic presented itself. I was told that any thought outside of the panic would be enough to give me what I needed to walk through it. Often times that thought was just counting, or praying. Becoming conscious of my breathing worked too, along with learning some simple breathing exercises. Point was that 100% my mental focus was no longer on the attack. Even 2% going to something else would make it more tolerable. It took practice, and a lot of uncomfortably doing that, but over time, it absolutely worked. Wasn't a quick immediate cure, but a cumulative one.

I actually remember one truly defining moment for me. I was a little over a year into recovery, and doing great. Even enrolled in a college course. One evening I had a full blown attack in the classroom. I applied the above, which got me through it, but my defining moment was the next day when I had to go back to school for some other thing. I had to pass the classroom where I had my attack in order to get to the office I needed to get to, and I instinctively started to reroute myself. The thought of passing that room kicked up anxiety. I stopped, rethought, and kind of committed to myself that I'd never again let panic deter me. I walked passed the classroom, felt the anxiety, and was fine afterwards. Took me a year to get to that point, and some practice still afterwards to fully recover, but 29 panic free years after I can say it was completely worth it. I went from being a guy who couldn't walk to the corner store without being drugged, to one who has flown to many parts of world, and traveled the US extensively. I never even dreamed of doing any of that. Didn't want to.

There is lots of info here and on the internet on ways of holistically addressing anxiety, panic, and agoraphobia. I'd advise you to be kind and patient with yourself. And keep a very open mind.
