Physical or Mental- Which is Worse?

My sister, having recently birthed 5 babies all within nanoseconds of each other, at least in the perspective of eternity, has the gall to tell me I am an old woman who forgets what having young babies is like if I think the angst of college kids even BEGINS to compare. This is actually an interesting metaphysical question- which is worst, physical or mental exhaustion? Whenever faced with mind boggling dilemmas like this, I seek answers from my two favorite sources- the Bible and a caffeine high. In the morning, I often have the benefit of both sources at hand, thus you reap the reward of both enhanced cognition through chemical means (caffeine is the most potent and only drug I use), and the Holy Book.
It is interesting that in John 16, the beloved disciple seems to agree with sister Holly. He says in verses 21-22, "A woman giving birth to a child has pain because her time has come; but when her baby is born she forgets the anguish because of her joy that a child is born into the world."
At this point, if I know Holly, she is dancing around the living room with a smug, self satisfied look on her face singing "I was right, I was right, ding dong I was right...." while her five little children look on and glance sideways at each other, making circular movements behind their hands and then pointing surreptitiously to their whirling progenitor. However, note John says that this physical anguish is forgotten.... and maybe the joy of the newborn babe as well in direct proportion to the height of the dirty diaper pile.......
But contrast that anguish which is fickle and ends as soon as that squirming little bundle flops out, with the mental anguish of Paul in Romans 9:1-3:
^"1I speak the truth in Christ—I am not lying, my conscience confirms it in the Holy Spirit— ²I have great sorrow and unceasing anguish in my heart. ³For I could wish that I myself were cursed and cut off from Christ for the sake of my brothers, those of my own race.."

His anguish is UNCEASING.....and what causes it? His despair that his own people do not recognize Jesus for the Messiah that Paul knows Him to be.
Physical exhaustion stinks, there is no doubt about it, and given my choice between birthing a baby or taking a nap, were a baby to emerge from both, I would choose the nap. But all physical anguish eventually ceases.... now the ultimate earthly ceasing may be frightening, but earth is just the introduction to eternity. However, mental anguish when it involves unsolvable problems like squishing the college boy back into the baby size package that used to crawl onto my lap and beg for me to dispense my love and wisdom upon him.... that anguish never ends, and thus is the worse type.
This would not be an inspirational blog however if I leave you with that morose ending, so I will finish that verse about the anguish of birthing babies, and leave you with the glorious and hopeful conclusion:
"Now with you, now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy." John 16:22. Jesus died and there was no hope, but then 3 days later as He stepped out of the grave, joy that will not fade entered our hearts.
