Coping with the Loss of a Father Figure

I lost my dad, going on 3 years ago this October, tonight/this morning I was so heartbroken he was taken from me so soon after not being able to see him for 5 years since I was in the system, I had a breakdown just holding his flannel screaming into it asking why he was taken 3 months after we started to talk again. He had stage 4 pancreatic cancer and he had to fight so hard, but he couldn't cheat death this time. I guess whoever / whatever higher power needed a hero. I still question to this day why he was taken so soon. I'm trying to live with the hurt but it hurts so bad. he wasn't my biological father but he stepped up to the plate when I needed one. Anyone else have someone like that in their lives? so special you consider them a parent? if so and you've lost them I'm here and I'll listen.
