You are such a good son! I can feel what you feel, and I can tell that you are a good man. That is why I would like to spend some time to help you out.
I have been here for more than 20 years, but my heart is still in China. I can't just go back, because my son needs me here now. Life is always hard, depends how you face it. If you are not happy, no matter where you are, you will not be happy.
I know you feel that you own your parents, and there is not much you can do for them now. If you stay with them, they may not be happy because they may want you to have brighter future by staying in Canada.
I think the only thing you can do is praying for them, so that they will be in GOD's hand, so that they will have a happy and healthy long life, so that you can keep going back to visit them. And you yourself also need to know GOD, to rest your heart in HIM, to have joy and peace from HIM, and most of all, to get the wisdom from HIM.
I really hope you will enjoy your life everyday!
email me if I can be more help to you.
