Definetly a form of TARGET PANIC! Very simple in one way.........try drawing your bow with no arrow(keep your finger behind your trigger)......can you aim and hold on the target? I'll bet you can!

The bad news is I really can't tell you how to fix it. I've struggled for years with this. I think its often caused by getting into the habit of "punching your trigger". You may also have too long of a draw length or too much poundage.

Good Luck!
