I did the same with my 7pt last year. 10 yards and I clipped a balsam branch. Was I PO'd. I new it was bad so I marked the spot I last saw him(It is really thick where I sit so it was close) checked the arrow and went home for the night. I called a couple of buddies and we went out in the morning at 9 am and found him at 9:30am. He was still alive but was just about gone so we punctured his lung so he would expire. He ran within 100 yards or so of my stand. We had no sign just followed trails and came upon him.

Good luck to you, hope you find her. It happens to us all and we all get upset with it but we just have to add it to the memory banks as a lesson learned and try hard to keep it from happening again.
