Grieving Process

It has been about a year and a half since I lost my dad. Not a day goes by that I don't think about him. I dream about him all the time. I would give anything just to see him and talk with him one last time. 
I have good days and bad days. Some days i'll think I've finally got a handle on it and other days I just completely fall apart. 
I miss him so much. I know time will ease the pain but it will never go away.
And somehow I'm ok with that. I feel like that pain is all i have left of him. Like a little piece of him still lives on with me.
