I agree, I was 15, when mine happened and everyone told me, thank god! You didn’t ruin your life! But, a year later I had my first daughter and she was my first blessing!
You definitely need a new friend. That was very insensitive.
You most definitely are not in the wrong. For someone to tell someone else that it's good that they had a miscarriage is not okay at all. I lost my best friend because she thought I was telling her she was a bad friend cuz she wasn't there much when I had my miscarriages and I had a different friend who had a miscarriage about the same time as me and we were support for each other. My best friend had taken it as me telling her that the other friend was a better friend when I didn't and 8 years later we still are not talking and I gave up on communicating with her. Sometimes people don't know how to be supportive in these moments and they let their opinions take over being supportive or they think these insensitive comments are them trying to be supportive when it's not. You are absolutely not in the wrong for being upset with what she told you. You went through something traumatic and are experiencing the loss of your baby. I have had 3 and I still think about who each and every one of them might have been.
I don’t think you’re in the wrong at all!
Not really a best friend then!
Wow! Absolutely not in the wrong who tf thinks that’s an appropriate thing to say! This is a heartbreaking thing to happen whether you have other kids/bonus kids or not that was still your baby and happened to your body)
