Greetings there,
It is very heartwarming for me to know that parent still do care about their young ones, even after they have grownup and supposed to decide their course of life and live on their own. Surely military service hit persons with soft heart real hard. Its do takes some time to recover, focus on life and rejoin the society as a good once again.
It would be much easy for me to figure out a way for him to coup with his experience during service forget his past and focus on his present and build a future if you provide me details about his life before service and his experiences during service. There must be piece of valuable information in his service record that will surely help us get him back on his feet.
It might take time depending on his current mental condition, motivation level and life priorities right now. Human psychology is very interesting, everything possible, there is no such algorithm to find success rate. However we try our best to get the things to work.
You may contact me anytime if you have any queries.
Looking forward
Irfan Ahamd Rana
