My mom died twelve years ago. At the time, I was very busy with my own life, raising teens, working. Her health had been poor for years and when she finally died, it almost felt like a relief.

Now my kids are living their own lives and I have miserable empty nest syndrome. I don't work much. I have a lot of time on my hands and I would love to have my mom around now, when I have time and energy to devote to her. I feel like I am really grieving for her, now.

I agree with nonightowl. Grief is very subjective, and talking with a therapist would probably be helpful for you.
