Give her the gift of a one hour massage. Give her a chance to be nurtured. Rub her feet. She may need to wallow in her grief longer than you can understand. Well, as her friend, please understand.
Healing takes time.
You can't rush it. It is easy to want to get her over this, but she has to heal in her own time. Help her see some useful purpose that can result from even painful loss. Show her that the future can be happy and hopeful. Keep whispering hope in her ear.
