I am sorry your first foray into WP was problematic or disappointing and think that this was based on a misundertanding. I am sure there are useful and fulfilling contributions you could make. Starting work on existing articles on topics you know about or have an interest in or starting new articles on simialr topics in which you have no direct possible conflict of interest might be best. WP:Notability and WP:verifiability are key things to think about, best wishes (  )
