My condolences to you and all her loved ones. My 13 yr old granddaughter's dad did this last September, and he was also my son's bff since kindergarten so I had known him for 32 years of his 37 on earth.....and I was devastated. Seeing his kids, his current wife, his dad and sister hurting so much and not being able to fix their pain was so horrible. I can relate to how you are feeling. 🫂
