With cancer, you will be bombarded with DIY treatments, literally everyone's an expert and I hate to pile on, but I have heard a lot of good things about the fermented diets.

I was recently diagnosed with an untreatable version of Intracranial Hypertension which is causing blindness and hearing loss, so, I'm basically turning into Helen Keller, which is scary as hell, but I'm very optimistic. So, with mind over matter, I doubt it will get much worse.

I'm glad that writing helps you, I've always found it to be the best therapy too.
Anyways, good luck!
