I'm sorry for you; I'm in the same position myself at the moment and its quite difficult. It would say just dont impose yourself on her, but let her know that you're there if she needs you. Does she have a big close family? If so, maybe its a bit early to go, but if she is alone, get round there with a "I'll not stay, but I wanted want to check tha you're alright and see if there was anything I could do...?" Maybe she wont want to see you, but she'll certainly appreciate the gesture.
