Need help with shock and grief?

I'd like suggestions on how to deal with the shock and grief of my husband's untimely death and heart attack 2 weeks ago. He was only 47 and we'd only been married 22 months. Everyone tells me to just stay busy, get out of the house, and talk alot to friends and family, and pray. We were enjoying the best years of our life and consumed in loving and enjoying each other and appreciating life. I do not work outside the home and don't care to. My 2 dogs keep me company, and I spend a lot of time with my daughter and granddaughter, but the hours go by slowly and sadly.
