my new bike?

[Antaresia]

So, I got a new bike today.

I was fit for it, but it still feels way too big. I can't stop it without almost dumping it - so I googled "standover height" and it looks like, for commuters, there should be an inch or three from the top tube to your crotch. There is NO space between my crotch and top tube, and I might add, I'm pretty sore there from the ride home.

It's a beautiful bike, but I feel like I'm going to fall off it. I can't even start on a hill at all. I'm also having a problem with the breaks, they seem to big for my hands and I can hardly get any leverage when I'm riding the hoods. But I'm not sure there is anything that can be done about that : /

So help me, did I get an ill fitting bike? Will I get used to this? All my riding experience right now is 5 months on a 30 year old mixte, so I have no idea if I should trust my LBS guy or if I was used as a dumping ground for out dated stock.
