There are a number of things other than bike size. The size of the bike pretty much fits your legs to the bike. Your feeling "stretched out" might be solveable by swapping out the stem for a shorter stem to bring the handlebars closer to you. I have yet to go to a bike shop to buy a bike where they don't do that without cost or at a minimal cost. A good bike shop should measure you, talk to you about your style of riding and pretty much tailor a production bike to you.
