Young widows support group in Brussels?

On behalf of a good friend, I am urgently trying to find a young widows support group that operates in/around Brussels. This friend used to live as an xpat here, but moved away for two years, has been suddenly and tragically made a young widow, and is thinking of moving back here with her 4 young kids. She will be here early next week and feels she would like to talk to someone with similar experience. I have given her the number of the Community Support line, but wondered if any of you kind people out there know of any support groups or anyone who has had similar personal experience that could help her at this difficult time. She will probably be based not far from Tervuren or Wezembeek-Oppem. If anyone can help, this would be much appreciated. Thank you.
