"Re-set, re-adjust, re-start, re-focus as many times as you need to." –FB Meme
When it takes years to get any results or footing from "re" it tends to get tiresome and can drag a person down. The only real action left is to keep trying. Rest for as long as needed between efforts to "re", but don't let the hope of a refocused life die until your last breath because with each heartbeat potential is renewed.
