Hi Cokie,
You don't have to move on until you feel ready to...everyone handles grief in their own way. If people are telling you that it is time to get on with your life, even if their statements are meant well, they are out of place. As long as you are able to function in everyday life (taking showers, going to work, getting enough sleep, eating okay), it is okay to still be grieving. If you are unable to take care of even basic needs of course that might indicate a need for professional help, but after losing my dad suddenly last month I can definitely imagine myself in your shoes 7-1/2 months out and even more than a year later. His death has left an enormous hole in the fabric of my life. My dad and I were also very close and although he had had some recent health issues, he walked almost every day, had a long to-do list for the day he died, and had things planned into next year. It seems impossible that he is gone, but he is. I keep telling myself, "I'm not daddy's litle girl anymore" like it's the end of my childhood (I'm 44!)
You don't mention siblings, but one thing that bothered me was that my mine have handled things very differently than I have. They took a week off, then continued to work, take care of kids, go to extra activities, etc. where I was barely functional. My grief therapist cautioned against measuring my way of grieving against anyone else's, even a sibling....since people are so different, the grief process is going to be different as well. It helped me a lot to hear that since I felt like I was a total mess. So definitely don't use anyone else's grief to gauge your own progress.
{{{{{hugs}}}}} to you.
