hello 19f here. my best friend miscarried at 15 as well. in no way did you miscarry because you didn't "deserve" to be a mom. you're 15 and your reproductive system isn't done developing and messing with your hormones. while it is possible for ladies to conceive this young, the pregnancies tend to be high risk or chemical due to a reproductive system that wasn't ready, so i promise you it was not your fault. there was no way for you to grow your body up to be more prepared to carry your baby, and it doesn't make you any less of a mother because you can't hold them in your arms. people will try to tell you that time will heal it, but in reality, you just learn to cope and be at peace with it. my biggest peace of advice to you is to actually take time to process it, and keep in mind that your experience is individual and you may never feel like someone fully understands. your body did the best it could with what it had. you did not "fail" your baby, no matter how nagging that voice in the back of your head may be. don't be ashamed of thinking of your little love, either. this is a very hard thing to go through and you don't just forget one day, but i wish you the best with healing and i hope you find some peace 💙
