Awesome advice.
When my grandfather was in I know he felt this way. He was an E9 USAF EOD. Served 21 years and was on the ground in Viet Nam. After that he was a pastor for 24 years. Married people, councelled them, helped those in need and never judged anyone or turned anyone away. He did SO much more than we even knew at the time, but still, there was something keeping him fighting and for the first time in his entire life he admitted being in more pain than he could bear.
On his death bed in the hospital my aunt held his bible and said, "Dad, is there anything you'd like me to read?" He said, "Philippians 1:21" and before she could find it he quoted it (see sig).
I didn't get it at the time, but when I studied further into it I saw this.
21 For to me, to live is Christ and to die is gain. 22 If I am to go on living in the body, this will mean fruitful labor for me. Yet what shall I choose? I do not know! 23 I am torn between the two: I desire to depart and be with Christ, which is better by far; 24 but it is more necessary for you that I remain in the body. 25 Convinced of this, I know that I will remain, and I will continue with all of you for your progress and joy in the faith, 26 so that through my being with you again your boasting in Christ Jesus will abound on account of me.
It was shortly after my dad said to him, while he was in a peaceful sleep and with tears streaming down his face, "Dad, it's ok. You're in too much pain. Go home and see mom and Kevin (his brother who was killed in a car accident back in '87). We'll be ok. Don't worry about us anymore."
Papaw passed peacefully after that.
