Thanks for the input on ways to overcome my fears of harming others. I never had this problem playing with a padded weapon - it must be that I subconsciously know this is fighting, not playing.
Your idea of visualizing a threatening foe is a good one. I'd forgotten I'd used visualizing an enemy to improve my softball hitting. I can't visualize my husband as a threatening foe, but others have crossed my path in the past that I could imagine striking at without pulling back.
Thanks for the suggestions!
