RE: Anyone suffer from this?
Target panic--absolutely. No question about it.
Had it, been there, got the t-shirt. Probably will get it again.
One of the things that worked best for me was making a long "bowstring" that you simply tie to the ends of the bow. The hardest part is getting it to the right length so that it is relatively taught when you come to "full draw." You ARE NOT actually bending the limbs of the bow to reach full draw--just taking up the slack in the string. No arrow is needed or desired. At full draw, you don't actually have any tension on the bow limbs, but the string is taut and you're holding correctly.
Now, you can aim and any target--even in the house under no real tension and take your time putting the sight on the aiming point and eventually release without dry firing your bow. I tried it and it worked great for solving my problem.
