It takes some time to get comfortable with hand quilting, so don't feel bad. I use a small hoop, maybe 8", and it's not super tight into the hoop. I don't use rocking stitches for super tiny work, just a single stitch at a time. The only time I do well with rocking stitches is if I hold the quilt with no hoop. I also don't use a thimble anymore, if my fingers get too sore I use painter's tape. LOL I also draw blood at times, so I'm with you on that part. You have the right idea by just practicing over and over, eventually it will be second nature.
