Hello,
I think you are mature enough to understand the realities and nature's Process of healing.
Please make a note for any Person if there is a
Head Injury (Very Severe Injury) Injury to brain or
Spinal Cord in 30% to 50% cases the Recovery will be very slow like a Crawling Ant taking time to cover a short distance.
Coming to your Father's Case as I was going on reading the lines I was feeling great k Soo many Improvements happened after such a heavy injury then Surgery and then Shunt-Operation.
You are Lucky enough that you are seeing your Father in Such a good Condition, so give Maximum effort physically to improve him further but not by force, pray for his further betterment.
But one thing I want to say, SAY Thanks to God for what are all the Improvements he had till now.
It is the Nature's such designed process of healing of Brain and Spinal Cord and also One's Own Will Power that helps in recovery in Case of Brain Injuries, because injury to brain take several months to heal about 30 to 40% but we saw Cases who went walking by themselves after 1 to 2 weeks of their admission and they were discharged.
So, do not force or pressurize your father Request him, Convince him, maintain his Good Mood always.
Never discuss any such thing because of which he gets Irritated and Disturbed. Remember one thing God has given back your father in Such a State after Passing through a Very tough Critical State.
So, accept the God's Gift and don't expect some Magic to happen Overnight. If at all if something Magic Happens overnight that will be your luck and God's extra Mercy but say thanks to God for what all you have in your father right now.
Be Courageous to accept the untoward things that comes in one's own life and we the human beings are here to absorb the untoward things into the heart and convert it into happiness that's the greatness of humanity.
So, do not get Depressed and give up. Be Happy and live the life in a Happiest way to the fullest extent.
Coming to any type of betterment or hopes in life remember, we can only wait till it happens whatever we want, but do not get Overstressed or Depressed if you are not able to achieve what you are willing.
Be Happy for every second of life for whatever you have, do not see that what you do not have. You can analyze or see what you do not have for only to pray for getting it but not for getting depressed or giving up in life.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Mohammed Abdullah
