Have you considered looking into a relationship with the Creator?
Have you looked into Dr. Clarks seizure protocols as well.
As with any protocol God allows it to work.
You have a creator and you are loved, just as you love your son and worry about him, but much deeper than that.
Sometimes we can be fully alive, yet dead spiritually which means nothing more than a zombie state. If we are not fullly grounded and connected to the source of all power and strength, love and peace, then we are bound to the worry and grief in this life.
