Hi,
After looking at the pictures on your blog, it doesn't appear that you bought too small of a frame. Rather, the drop bars may be exceeding the limits of your flexibility. Also, your comments on your blog ("bars needed to be rotated," "knees hitting shifters," "raising saddle height") indicate you've been trying to fit yourself to the bike. Did the shop do anything to help fit the bike for you? It doesn't sound like it. Like others mentioned, you'll probably want the services of a shop that can help you with a proper fitting.

Given your desire for a more upright riding position, you might end up abandoning the drop bars altogether and getting a bar that's more natural for riding upright. One bar in particular is the Albatross by Nitto. It comes in both aluminum (see here) and CrMo (see here) versions. Albatross bars should accept your current bar-end shifters, but you'd need to replace your brake levers. They don't offer all the hand positions of drop bars, but it doesn't sound like you've been able to utilize all those positions as it stands. FYI, I'm just passing this along as a possibility for you; you and the person fitting you will decide what works best for you.
