What can I do regarding Non-Self

After contemplating death while reading some articles on accidents, it dawned upon me (particularly strongly) that "everything" is out of our control. Everyone wants to be healthy, to have gains, not to have losses, but I recall feelings of helplessness/dejection in the inability to control when we are on the plane for example and there's turbulence and it's all in the hands of the elements, physics and fate. I contemplated more and more, the past times when I was sick, the various times throughout when I was in the doldrums of my 31 years of life. I can literally feel my heart has sunk as few notches. Though mentally I don't feel disturbed or weighed down, I feel overcome by the sorry fact that we (everyone) no matter how much we wished and tried our efforts, things are just out of our control, that our body, our circumstances, are all Non-self. I would like to get to a productive state from this place. Please advise? I feel a sense of defeated-ness acceptance regarding this Noble Truth, is there anywhere I can go from here?
