The socks saga

So I've been knitting ankle socks with sock yarn. This is my first time to ever knit with sock yarn. Here is what I have so far:

Now here's the bad part. Here's the other side of the sock:
You see that gap in the stitches? Its a bad thing. It means something is wrong with either the way I picked up the instep stitches or with the heel flap itself, or both. I was going to frog (rip out) until I got back past the heel flap, but I think I might have to frog the whole thing. I'm not very good at frogging-I never get the stitches back on the needles in the right direction. So, goodbye dear sock. I'll recreate you, I promise.
