I'm so sorry. I'm just seeing this as I haven't been online as much as usual, this is just devastating news. 

I am so sorry, and my heart goes out to you and Lisa and your family.

I have had a fair amount of experience with grief, and I'm here if you need me. And sometimes talking with someone who's not involved, and more or less anonymous, can be easier than someone you know.  

Feel free to give Lisa my number if you think I can help.
