Just something for next time...When you decide to shoot you need to consider the whole picture. If the deer is 35 yards out (and that is outside my comfort zone when hunting) the arrow will take about twice the flight time to impact as when shooting at 20 yards. If the animal has no idea you are there and is relaxed a 35 yard shot might be ok. If the animal is alerted and knows something is up he is going to jump your string. Now, a deer and move over 1/2 of his length in an instant and that double lung shot turns into a gut or rump shot pretty quickly. It sounds like you should have passed that time and paid the price. We have all screwed up big before so just learn from it and use that knowledge next time.
