This is huge, and possibly the most overlooked aspect of true healing. If your mind chatter is constantly reaffirming that you're sick, your body has let you down, your thighs are fat, your arms are flabby, your chin wobbles, well, that is never going to inspire your body to rise to the occasion.
These negative beliefs will settle into your subconscious and become blockages that prevent you from moving beyond a state of chronic suffering. As a former bulimic, I've struggled with self-image for decades. It wasn't until I changed the record and released the harmful affirmations (which came so naturally to me!) that I started seeing dramatic and life-altering improvements in my health.
You must harness the power of your mind in order to master your ailments. Establish a practice of positive affirmation. Explore hypnotherapy, cognitive behavioral therapy, meditation, or mirror work. Find a method that speaks to your innermost consciousness and that constructively disperses your negative energies and old stories, replacing them with affirmations that tell your subconscious that you are ready to move to a place of higher health. Allow your body to learn how much love, value, and purpose it holds. Remind yourself of this in as many ways as you can, every single day.
