Don't know if I have any great advice, but hopefully having folks let you know they want to send some (((((hugs)))) your way helps a little. I have lost both parents, and countless pets, and it hurts. I don't know that we ever get over the loss, but we absorb it and move on..... at our own pace. It might take a few weeks, it might take years.
Eventually I find that I can remember the good things more, and not focus on the pain of the loss. As a mom, I know I would want my sons to continue on with their lives, and surround themselves with people they love, and activities that make their hearts sing. But do what feels right to you. Nobody can replace a special love, friend, or family member. When ready, allow others who matter to bring something into your life. And the nice thing about our dolls is that they will wait for us.
