Marion, some of the most moving songs around have not come only from the experiences of the songmaker, but have happened to others and have been given a voice by someone who has the ability to give feeling a voice. Not everyone can. Sing the song. I agree that it might not go in all contexts, but many singers have songs they use, say, on a recording or in a concert mode but not in a pub gig or singalong circle. For a widely recognized example I respect a good deal more than the one given above, consider how many of Eric Bogle's songs deal effectively with a tragedy in someone else's life. Some of his are his own story (and some of those, such as "Scraps of Paper" are even after all these years painful to hear performed live), some are people he knows (the "Rosie" songs), some stories people told him (such as "Elizabeth's Song" about a cot death), and some he read ("Daniel Smiling" about child abuse, or the devastating "Claire Campbell"). If you know well the woman involved, sing it for her. If you do not, make her a recording and send it to her with a letter to the effect that you heard her tale and your heart goes out to her, you had to write of it and hope your song can possibly give some comfort to her and to others in a similar situation. A line in "Elizabeth's Song" mentions that while people sometimes refrain from mentioning a tragedy and "reminding" the sufferers, they certainly have not forgotten and speaking of it does not make it cut any deeper but can only help them heal. You will eventually find out if it is a song you (or others) will continue to sing after this event has receded. Sing the song.
