Hello Savannah .....
Can I ask just one question?
What would your Dad want you to do right now?
I have two daughters, and much more distant than I would like with one of them. I think there is or should be a special kind of relationship between a Dad and his daughter.
It sounds like you had that. It is something to cherish. I am sorry for your loss, but hope you can put everything into perspective in time. A counselor would be a good start ... and/or a group for support that's made up of people with similar situations ... like the loss of a loved family member.
The very best wishes to you.
Rob and Gizzy
