Dear kora ,

 I am agree with you in these points and really am grateful for you that you opened my mind for that especially kct syndrome as i asked him after i read your comment about any separation or abandonment happened for him he told due to unstable situation on his work and many layoffs happened last year he decided to send his family to there home country until his situation become ok or find another job and he suffer too much from these loneliness.

so i will suggest in the intervention methods in the next sessions:
*to bring his family again to live with him or to spend long vacations with them( social)
*and i will try also to integrate the believe that although its not good you live alone without your family but you can accept the situation as its temporary and  you should know that your happiness comes from within you ,you should find your own resources to make yourself happy with or without your family(emotional, soul)
