How would you react

If you lost your child because someone who was supposed to be their friend murdered them. Not only murdered your child. Sexually assaulted their body after they did that. You never get to watch the baby boy you grew turn 17. You will never get to see him graduate. You will never see him go off to college. Fall in love. Possibly have a family. It's only been a few months since the verdict and the person who murdered them was sentenced to death which death row takes a long time. He'll probably be on death row for 10 to 20 years and even then there's a good chance it could get overturned. You go through all of that pain. You make posts online about missing your child and hating that their life was taken. Then the mother of the mother of the person who took you child's life has the audacity to reach out to you and ask you to please stop talking about the situation on social media and to understand that you BOTH lost a child just in different ways. How do you respond because I said some things that are so unlike and part of me feels guilty for letting myself send that message but another part I just feel like "How dare you?" "How dare you tell me to stop talking a lot how your child took my child's life?" To compare me losing my child by your kid killing mine and you losing yours by yours getting sent to prison. I feel like this is wild. Tell me am I insane and blinded by grief or was she absolutely out of her fucking mine?
