Wow So many things mentioned in the five or so posts above.
Many people are relieved when they discover grieving styles, some of us lean toward being an "emotional griever", we express our grief openly, tend to cry alot. Others are "cognitive grievers", they are more the doers, want to keep busy, tend to handle what needs to be done, do not show their grief, their emotion, it does NOT mean they are not grieving. It is hard to understand those that grieve the opposite to how you grieve. Be kind, give space.
Some people write to their loved one, short daily notes or longer letters.
Others get value from reading about grief, expanding their knowledge, Alan Wolfelt is one of many great authors, with books that will address your specific loss, check out your local library.
Look for grief groups in your area, only those that have had a loss and espcially a similar loss can say, " I understand, I get it." For many a grief group was the best thing they could have done.
Don't be surprised how long grief lasts, I would say that my grief will never end, it will change, I can still live a joyful life. Find the support and do the work to actively grieve, avoidance does not work.
In our society so many people don't know how to support you, feel uncomfortable. Don't be surprised when good friends aren't there for you. I didn't judge, I shared with a few that I was hurt by their lack of support, asked for what I wanted, had a conversation, yes it was scary but worthwhile. You choose, surround yourself with those that are positive in life, that are good to around, avoid the others.
I can go on, but time to stop, hope has been some help.
