Should i keep this or bin?

You should never throw away the stuff you write, even if it makes you cringe! You might pick it up again in a few months time and think "Christ, I've come a long way since then" or "Wow, some of this stuff deserves work" and then go back to it. I'm sure there's never been a writer in history that hasn't hated a lot of their own work, it can be a positive thing, helps you improve.
