Overcome blindness?

I FOUND OUT I'M LOSING MY SIGHT AND IT SCARES THE BEJESUS OUT OF ME. I DECIDED TO GOT FOR A 2ND DOCTOR AND SEE IF THEY AGREE. WHAT I HAVE IS PERMANET. WHAT WILL MY LIFE BE LIKE IN THE DARK? TAKE CARE OF MY HUSBAND DAVID AND OUR BABIES. HE IS BLIND FROM A FA-18 HORNET ACCIDENT. HOW CAN DO ANYTHING FOR HIM WHEN I CAN'T SEE? SO I'M IN A ROCK AND A HARD PLACE. WITH NO WAY OUT. IF I ASK FOR HELP THEN I WOULD FEEL LIKE A FAILURE. (NAVY PRIDE) I TOLD DAVID THAT I FAILED AS A WIFE AND MOTHER. HOW CAN 2 BLIND PEOPLE RAISE 3 BABIES WITH 2 ON THE WAY? ANY ADVICE WOULD BE GREAT
