1. Don't panick

Can you post a video clip of your shooting?

There are a few things that I tell myself when I start shooting bad. Maybe it will help.

Take time in between shots (at least 20-30 seconds). Think about each shot and move on.
Keep bow arm up. As Ferguson says, as in a vise.
Do not flinch upon release (I got a habit at times)
Pull from drawing elbow, not from fingers. DO not let fingers release the string (they can't get out of the way fast enough)
Align everything, tip of arrow, nock, back of drawing elbow.
Back tension, back tension, back tension

Go back to 5 yards until you can stack them, I bet it doesn't take long, then move back 1 yards at a time.
