Any one have any advice on dealing with loss and grief?

I don't really have anyone to talk to. My Dad passed March 6 from Sepsis, I watched him twice a day, everyday for two months struggle in hospital, then I arrived at afternoon visiting time to find my Dad had took a bad turn in the night and the nurses said they never had TIME to CALL us, by this time he had JUST lost his ability to talk, so I feel they stole our last lucid minutes with him, then I spent the next 12 hours comforting my Dad as he passed away. He was my BEST friend. He fixed everything with a coffee and a cuddle, he understood my personality disorder and was the only person I could speak to. I am heartbroken now he is gone. Can any one relate of give advice on coping? I am now also my Papas full time carer since he passed (my Dad and I split caring between us before he got ill too) and care for my 3 year old daughter, so it's hard to even find the time for myself, or to grieve.

Thanks to anyone who listened.
