I feel grief with my mom passing away in jan. from a traumatic head injury. what should i do?

Several options: Grief is a gradual healing process for all of us. There may be grief support groups through your hospital, church, or other places in your community, and participating in one may help. You can also get individual support with a grief counselor or psychotherapist. Hopefully you have family/friends around you who knew your mother, and can share stories and memories. Wishing you peace.
