Gosh! i know exactly how you feel. 2 weeks ago i had a doe walk up to me and i hit her at about 15yards. This was my first deer with a bow and i was really excited. Any way i thought that i had made a good shot buti let her sit for about 3 hours. after we took up the blood for about 250yards she bled really really good then after that nothing. After lossing the blood we looked for atleast 4 hours for the next blood. Then after all that failed we looked for the body for about 2 hours. We found nothing at all. All i can say is i hope that she is still alive.
