Self compassion is key when you have a chronic illness of any kind. Life is beating you up enough as it is, so be sure you are not making it worse on yourself with poison thoughts and feelings. Self care, self love, self compassion, spiritual practice, and support from others is what has kept me alive.
Get all the junk out of your diet. Take magnesium. Exercise when you can. Take baths. Rest as much as you can. Listen to your body and be kind to yourself.
