Worry and anxiety leads to depression when they overpower our mind . We become prey of our anxiety when we are afraid to "let go". Afraid of losing something or other , by letting go of what we cannot control is the cause of worry. Being satisfied with what we have and who we are, will eliminate the constant anxiety that takes a toll on our lives.
There is lot of truth in what you say. It is the fear of losing- status, family member or something else- that causes worry. If you just overcome fear, most of the anxiety will vanish.
That is rightly put. I think, the fear is more strong that any other thing. If there is no fear, I think, there will not be that much big amount of anxiety. Btu still for other reason, anxiety will stay.
