Discussion: I was desperate for conventional medicine and decided to seek self-healing treatments, but there is a wide variety, and I have no idea how to get started.

I recommend using the attached article that elaborates extensively on the mental and physical treatments required for recovery from chronic heart disease. At the same time, the difficulty indicates that you need (especially at the beginning) a professional to guide you. (Highly recommended) Given the appropriate terms (mental & physical), all chronic acquired (non-genetic) diseases are curable!

I recommend that you try in the first stage to contact a qualified naturopath who will accompany you throughout your recovery. The "chemistry" with the therapist is essential. There are about 100 alternative diagnostic and treatment methods. Indeed, it is not an easy task to choose from all the variety.
