Remember the good times you had with him and be thankful you have those memories, hold them dear. Remember no loving parent would ever want their child to self destruct over mourning their death, we are all going to die someday, it's a part of every life. What did your dad want for you? To be happy and healthy, to percevere, to make the most of YOUR life. Get out with friends, do some new things, distract yourself away from mourning your loss. Volunteer, make some new friends, help others less fortunate. The pain will subside in time, your overpowering sense of loss will diminish. Life goes on, the living need you and you need them. Ask God to help you heal, to take the intense pain away. He does work wonders. My dad died at age 50, I was 27 and ill equipped to deal with it. I buried myself in my work for a while, fortunately I had a loving mom, a compassionate girlfriend and a few good friends to help me through that tough time. The sense of loss of losing a loved one never goes away but the relentless pain and anguish accompanying it will subside in time.
