Yes, Sarah, I lost my dad when I was 11. He died of a massive heart attack at the age of 39, with me right there holding his hand. I remember it like it was yesterday, and I will turn 50 later this week.
I believe I was in shock or a brain fog for about a year afterwards, and left in a wandering state for a long time.
I accepted the Lord as my savior in my later teens, but had no one to guide me in what to do next. I know His hand was protecting me and He was calling for me, but I ran away. Through a couple of selfish stepfathers my mother tried to replace him with, I just went through life trying to do things my own way, figuring everything out on my own.
This caused me more great heartache through a failed 9 year marriage and ugly divorce, and then finally, in my mid 30's I found the woman God had intended for me all along, she guided me into a true relationship with the Lord, and with Him as the head of our marriage, we will be together until the end.
So, what I can tell you, after having gone through it and coming out blessed on the other side.
First off, death is not an easy thing to come to terms with, but God does have a plan for your life.
I never really found peace about my dad's death until I finally submitted to Him, and I can see how He used that for my benefit later in life.
We do have the most Loving Father you could imagine and He desires a personal relationship with you. Pray to Him, talk to Him, and let Him guide you through life.
You will still have struggles, heartache and pain, but it's much easier with Him as our guide in everything than to go it alone.
So, I will keep you in my prayers, and time does heal.
One of my favorite things to read when I struggle is Psalms 91, it always lifts my spirit.
