Life can be pretty much unpredictable. You do something and something else happens. When you try to do something good and then things turn bad. Your all dreams and expectations can turn something worst. That point of your life demands change. What you do is not working. And that is where you are meant to change as well. It is going to take effort for you to make such changes that does not create the same pattern of bad experience. If something is not working, change it, still same result happens, then you need to change more things to change the result. :)
