How can you expect them to concern themselves with your problems when they are so blank with troubles of their own?

It is not always good to expect from people. There is much more satisfaction in expecting more from yourself when you know that you can do more. Learn to be independent. We are free humans, safe from slavery unlike in the old days. There is much more freedom available for a majority of the people around the world. Therefore, one must take advantage of this. Learn to stand on your own feet, and look for people who can actually be available and will be concerned with your personal problems. Maybe you are the one who can help them before they can help you. It is a give and take situation sometimes.
