<human>: Summarize the given text in a few sentences.

My girlfriend lost her father on Thanksgiving, fairly suddenly to cancer (he was stage 4 when diagnosed and he died within 2 weeks after). These two were very close, with a much deeper bond than a regular father/daughter bond. My girlfriend is devastated. She goes to a grief counselor but it seems to get worse day by day.

Here are some specifics to our situation that may be helpful... My girlfriend gets really sad when she thinks about how I never got the chance to meet her dad. This is a particularly large source of grief for her, and one she talks about often. Also, she LOVES to talk about him. She says that his name is music to her ears, and even though it makes her sad, she loves talking about him and reminiscing about him. She thanks me every time I bring him up. 

She has moments where she is just honestly hysterical. Hearing her cry just breaks my heart so much, I simply can't bear it. I would give anything to trade places with her. During these times she is just inconsolable. 

Things I have been doing/planning on doing so far: talking about him with her and letting her know how much I desperately want to be a part of her relationship with him, since I never got to meet him in person. I signed us up to run a marathon together that benefits cancer (she is a runner and has always wanted to run a marathon). I have made arrangements to visit her over the summer (we will be long distance) to visit her dad's grave with her for the first time on his birthday. 

Thank you all so much.
<bot>: Girlfriend unimaginably grief-ridden, I can't stand to see her so sad and would do anything to fix it. I need advice for how to help her.
