I totally agree with this guy. Your father is ill and your mother cannot handle everything alone since both are elderly. Come back and serve you parents, InshAllah you surely will be rewarded for this. I have a firm believe that if you serve your parents you'll surely be rewarded by ALLAH SWT and there's nothing more powerful than the reward by the creater of this world.
Let me share my story just to make you feel that you're not alone. I was jobless since the time I graduated from univ with my engineering degree for 3 years straight...yes 3 years..I tried hard used all resources but no luck neither in dubai nor in karachi. But one thing I always kept as priority that is my mother, I decided never to leave her alone for my future and my career. I was asked by my brother to come to canada for studies and my condition was that I will come only if ammi goes along he agreed but I didn't get the admission in masters though. Meanwhile I started studying CCNA and then CCNP in the summer of 2010. Went to dubai to find a job since my mother is resident there so going dubai was not much of an issue, got a good response but I was lacking in experience.
I came back asked a friend to look for a job for me, he was working for a mobile operator and forwarded my cv for a vacancy. I had an interview on the monday and my mother fell ill and was admitted in hospital on friday and I was there till sunday in the hospital with her, I was not worried about the interview and was not prepared either and I cried a lot for my mother, she came back home mashallah on sunday and I went for interview the very next day and surprisingly got selected and started my duties from the next day. Believe me there was nothing I did, it was all reward from ALLAH SWT for my care towards my mother. I got a handsome package in the company with an ideal position in a telecom sector for me in respect to learning and worth. I am telling all this to convey message to those who leave their parents for their future, they may become successful but to me that's all fake when you're sacrificing wishes of your parents for your future. Ask a mother whose son is living abroad how she feels even my mother cries for all my siblings living abroad. In the end I will again say come back, look after your parents, meanwhile improve your education in Pakistan then when things get better go wherever you want to go. ALLAH tallah hum sab ki hidayat farmaye aameen
