Great topic. Very thoughtful reflection.
Face [your demons] head on, with everything that you have got. Gather you will, your courage, your determination, your hope, your desire, your dream. Use them in the fight. Face what is troubling you head on, and then, at the end of the struggle, find a way to finally move on.
Of course, this always works better when we have some help. Not necessarily professional help. Sometimes all we need is a friend to talk to, to talk us out of a bad decission or out of our paralysis to face our addictions or apprehensions.
I compare this with working out/doing excercise. You may spend months, even years planning to start a routine, a training regime, and it is enough to find a friend to push or drag us to actually get started.
The pushing motivation may came from the most unexpected source; it's just a matter of keeping out ears receptive to hear the good advice.
