Whichever way you look at it you are entitled to your own opinion, frustration is out of the question. I see no sense in waiting for 10 years to emigrate, to me it is crazy and that is it.
I applied 2007 but can I switch over to PNP even whenI have applied under the skilled workers category?
My opininon is that I see no sense waiting for 10years either but the Bible says my people perish for lack of knowledge (I didn't mean to be hard).
Your application is not up to a year old yet; nothing should stop you from withdrawing it and file via PNP after checking to confirm you are qualify for that route.
All the best!
