hi sleepy amethyst (I like your name) I am glad that your husband decided not to go the conventional route.. and I understand your feeling grief and anxiety about facing the world now apparently knowing what you do about mainstream medicine.. but it's ok, you are not alone and you're only uncovering the reality of what truly exists and is supposed to be here.. and there are many others unraveling this path too. I however do have to say that I don't think gerson therapy is the best or most ideal option, but it is lightyears better than anything "modern medicine" has to offer because most of their answers, or guesses, just cause more disease and disorder..
So I think that it's possible to get a lot of healing following gerson protocol but if I may add some advice, I'd first suggest to replace the coffee in the enemas with a non-caffeinated herbal tea instead. There are so many tremendously wonderful healing herbs available to consider. I won't go too deeply into it against gerson if it isn't going to help you and your husband find something even better though, the last thing I want to do is contribute to your uneasiness.
but of course if I could add a couple things I'll say raw food, especially fruits, go a long way, and according to the most successful and impressive healer I've found in my many years of searching and research, Dr. Robert Morse, fruits are essential to healing, and herbs are an integral part as well.
I've studied a lot of healing modalities and many will work and help, but as you've got the right idea with the enemas, it's about cleansing the toxicity out of the body and allowing it to heal itself.
I could go on a lot longer about all sorts of ways to heal, but I will stop there about that unless you ask me to continue or talk about something specific.. Lastly though I will say since you asked for help coping with your newfound understanding, there is a simple technique that if you're up to trying it you may find extremely helpful. It's called EFT (Emotional Freedom Technique) and it can profoundly help you process emotions and thoughts and better deal with all sorts of situations. it is clinically/scientific proven even to be effective for many things like PTSD, depression, anxiety, phobias, etc.. but it's just sort of a general panacea for the soul and mind.. and involves tapping on a handful of acupressure points, primarily on the face, and saying a sort of affirmation such as 'even though I feel ____ about ____ I deeply and completely accept myself anyways'
that's not verbatim but you can follow along with many youtube videos or make the script up yourself when you get the gist of it. You may feel silly doing it but trust me please try it for yourself and see.
I'd also suggest joining online communities where people are into these "alternative" natural healing modalities so you can feel comforted by the presence of others who've also been awakened to these truths you're starting to face, and you can hopefully benefit from their experiences and stories they share.
If you want to check out Dr. Morse he has hundreds of youtube videos, and he is spiritual as well. I admit he tends to ramble off on tangents in some of his videos, but hopefully he speaks to you as he has to me. the truth is though I first listened to him years ago and have remained loyal to him because he makes so much sense, but a lot of what he says didn't really sink in to me til the last year or two.
anyway, here is one of his older videos, Cancer- The Raw Truth

but feel free to peruse his other videos if you're so inclined, he makes many answering and addressing questions people send in
I want to share two more things from him, sorry if it's too much
I think this site is amazingly useful though. It's a search engine for his videos (and a few other peoples' you may find in the search results but mostly it's a library for his own) so you can type in a key word and it'll pull up videos that mention it, with timestamps and summary of what was discussed in those minutes of the video

and one more thing, here is a page with testimonials by people who have been helped following his philosophy and advice

Thanks for reading this. I wish you and your husband the best. I'm skeptical of anyone taking what I say seriously, which I imagine you understand considering you just woke up to the reality of healing and what most people believe, but if you want to talk to me any further I will be happy to
