I've struggled with the same frustrations. It's easy to trace a historical line through several notable moments and thinkers and conclude that an alternative experience of life is possible, but I increasingly suspect that:
(a) per your correspondent, if "...nothing is real[,] everything is constructed," then it's because there's a fundamental function of human psychology that compels us to perceive dramatic narratives all around us and weave ourselves into them;
(b) this function is what the society of the spectacle is built on and exploits;
(c) it's seldom realistic to escape these mechanisms. You can perhaps escape the _society_ of the spectacle by removing yourself to more isolated and "authentic" circumstances, but I'm not sure you can permanently escape the compulsion to live yourself within spectacles of your own creation. If that's true, there's the small consolation that it's authentically human to do it.
...These are just my thoughts, now, mid-life, after many years of contemplating these things. For another (perhaps surprising) authority on the subject, I recommend Proust.
