Oh waves, I'm so sorry. I think a letter is a good idea just to let her know that you are available to listen if she'd like to talk, or have a shoulder to cry on even if that shoulder is a distance away.

I attended our survivors support meeting last night and was so in awe of a family who is only months into losing a loved one to suicide. They are fortunate to have each other (a big family) to cry with and lean on and listen to.

You can offer great assistance in your willingness to listen when she wants to talk...and remember, that might take a little time before she is ready.
