Thank you for sharing this story. I'm sorry you and Kimchi are both suffering but how cool that you're doing it together! Thought I'd mention that you might want to consider an alternative therapy that could be a lot cheaper and can often produce better results? I am a homeopath and have seen astonishing things in my practice, one of which is to completely cure asthma (yes, cure, as in symptoms go away permanently in some patients).
It works on animals as well as people, it's gentle but powerful, without harmful side effects when prescribed by someone well qualified.
Perhaps you could find a homeopath in your area, or one that works online and can send you the remedies.
Thanks for sharing your story!
