How do I convince myself I am just a story? Listener question

 I've scribbled pages so far, I'm not done, this is what I have, still a bit fuzzy, help me out or pull me back from the brink.  .... and thanks Clare.  All my problems have the same base; not good enough, not smart enough, lacking in some way or another.  All are formless - ideas and thoughts floating around in my head.   My bio-computer brain believes the story it's telling itself and looks out into this world of form to see what others do to be happy.  I give it a go.  Alcohol, drugs, sex, becoming successful, acquiring the right material goods, getting my body into the best shape, being unique, having an interesting story .... eventually it all fails.  I give up and just look forward to having enough money, health and maybe companionship until I depart this miserable world.  (fuzzy part) No matter how many times I throw myself down the stairs I’m always pulled upright and given a do-over.  In all spiritual studies I have been led to there is talk of separation of who we really are and what we believe we are. I’ve come to some awareness of this.  I realize the self I call ‘david’ is a story, created around experiences, influenced by others, given meaning, value, and believed to be real & true.  (very fuzzy part) Through  these exercises I’m seeing practical solutions to my problems in the world of form.  But how do I convince myself I’m just a story, I’m just awareness showing up in this body-form, there really isn’t any separation only a misunderstanding I forgot to laugh at.
