Ash--forget about the 'targets' for now--and just shoot at hay bails or a the block without any paper targets.
You're concentrating too much and blowing the shot.

Just relax, stay calm and shot at a target that's about 24" X 24"--don't try to hit a spot--what you want to do is to get the hang of the release and getting that shot off.

Stay ancored until your arrow hits the target, hold your shooting form.
Hold your shoulders up and maintain a proper stance--feet about 12-16" apart and bow-shoulder 'facing the target'.
Don't move away from the bow when you release the arrow, this only inflates the problem.
Stay calm--don't try picking a spot just yet--just practice a smooth release and not tense yourself up--take a deep breath, exhale a little, relax, remember to keep your form, same ancoring point on the side of your face, and squeeze.
Do this until you're comfortable, until you're not jumping the shot--as long as you want--could be weeks----get the hang of your form, bow, release and comfort level---then try aiming at targets.
Everything takes time----only those exceptional one in a million shooters can 'robin' arrows within a week, for the rest of us it's all about--'practice--practice and practice'-- it will come!!!
The best of luck bud!!
