My sympathies are with you. One of the things I learned from similar situations and have seen my children learn is that these experiences will change you for the better if you let that happen.
You learn what life is truly about and will find as many of us have that there is always time for the people in your life. Time to make their life better and time to enjoy their life with them. Blackjack has it right, listen closely and life will improve no matter the physical outcome.
"Do not go gentle into that good night - rage rage against the dying of the light."(Dillon Thomas) works for me.
