Stress raises cortisol levels ( the stress hormone) which robs your body of certain vitamins and minerals. I would get plenty of B and some D vitamins, with additional supplements of magnesium and omega 3's, which can all help physiologically.
These other suggestions of prayer and scripture are also helpful, as well as, sunshine and Gods creation. Get some alone time with God in nature with some sun and wind. These can help physically and spiritually. Another boost of spirit, is give of yourself. Sacrifice your time, talent or energy, for someone, or something, greater than self.
A whole body approach helps you heal quicker, and have a reduction in symptoms.
May God bless you, and use what your going through, for your good, and His glory.
