Hi there, I am sure your dad was everything to you. What it means is that he was a good dad and must have been involved in every aspect of your growing up till his demise. I know for sure that his involvement in your development was to make sure that you are able to stand on your own two feet one day and to be as strong as he was to hold someone elses hand. Healing from such a loss will definitely take time. I would like to encourage you to take life one step at a time hereon knowing that what your father always wanted was for you to always be okay even after he is gone.
