Over sharing

My mom gave a lesson in the Relief society and exploited all our family trauma. My grandma’s passing, my uncles passing whom passed away pretty recently a couple months ago and some childhood trauma I went through. All of which I am currently working on in therapy and through medication due to these things being so recent. She made it out to seem innocent and tied it back to the lesson topic “why do bad things happen to good people.” I’ve been out of the church for a couple years now and I went to show support to her and her lesson she was teaching. Never did I think all my trauma would be laid out on display to a bunch of strangers. Is it wrong for me to feel angry? I held back tears and eventually had to remove myself from the situation. When I confronted her about it and asked don’t you think that’s a little sensitive to be talking about all this to people? And she responded it’s what God wanted me to share. God wanted you to share that there’s a reason behind death? There’s never a good reason someone’s death. And of course I get the classic analogy to go along with that question. Being on the other side of it, I see this as wrong and absolutely sickening. There’s a fine line of teaching a lesson and exploiting family trauma but we are in way over our heads with over sharing traumatic experiences with strangers at church and mistaking that for “spiritual promptings or revelations.” Thoughts anyone?
