I lost vs a Yugoslav attack

I hope to get better at the Dragon and the Yugoslav and the rest of the Black side of the Sicilian.  Last night I made a horrible mistake in the Dragon.  There was Ne5, exposing my Q to the other Q, which I was too sleepy to notice, so then it was goodbye Q!  Then I resigned.    You can tell I am far from expert on this opening.  It looks like I should have retreated Qd8 to guard against the fork.  After Kb1 I had to do something about Ne5.

I'm impressed how much more material is readily available than when I used to get regularly crushed by this opening in high school.  When I was in high school, there wasn't even Internet yet.
