I am not a doctor, I have no medicinal training. In no way I should be looked to for professional psychological, or well being advice. However, I can recommend you a book for your illness or Malady.
There is a novel for every condition that a person may face. Reading is a particularly focussed activity, reading requires attention. The right book at the right time in the hands of the right person can inspire, lift and in some cases save the life of its reader.
Reading the right novel when you are unwell can serve as a reminder that they are not alone and seeing in a mirror themselves reflected and refracted from another points view gives perspective.
What you consume as food obviously impacts your body and what you feed your mind has equal impacts.
