Hi Shurtugal and welcome to the forums.
All poetry posted on this part of the forum is original work (ie. stuff we've written ourselves!). Most of us haven't been published either so you're in good company, and you're most definitely a writer as long as you love doing it.
We always look forward to seeing new work so post away (just so long as you stick to the forum rules - no more than one a day!), and I look forward to reading your work.
