I agree, that first year is the hardest, I didn't feel like myself at all when mom died and then Daddy died 8 years later. To be honest, I still have times when I cry over them, we were best friends, they were my cheerleadersand I helped them when they needed me no matter what. I wish they were still here, there's so much I would share with them.
LB, don't feel bad about grieving, it's normal, if you didn't feel this way then I would wonder what's wrong. I took the death of my daddy harder than I did mother's death, yet I loved them both dearly. I think maybe because dads and daughter have a special bond, plus, we (or I did and still do) now feel like orphans. We were with them literally from the day we were born, so a major part of us is missing now. True, time heals, but I don't think a person ever gets over the death of a parent(or any true loved one).
