I salute you @surpassinggoogle for the unconditional love you have especially to your dad. Not all the children can do what you did, I'm sorry to say this but I've seen a lot of selfish children who disregards their parents especially if the parents are sick. Some avoid to take care of their parents thinking they will just be a burden to their lives. I really admire your love and care to them. I really hope that your father agrees to travel so he can be on your side soon.
