If you feel as though you need to go to the hospital go. Make arrangements for your son and do what you need to do. Calling your H will not help you, nor will it "show" him how much he's hurting you. You need to function as if he is dead and don't depend on him for anything.
"Success is the sum of small efforts, repeated day in and day out." Robert Collier
"One's best success often comes after their greatest disappointments." Henry Ward Beecher
