Miscarriage

Hey girls, Im 17 years old and i have a 8 month old baby who i love so much😊 but i have a younger sister who is 15 and was pregnant probably was only month or 2 pregnant and she had a miscarriage and she just told me, she hasn't told anyone and im not going to tell anyone either but i just feel so bad she showed me a picture and i could see the fetus, idk how to feel, she's actually really good, it happened about a week and a half ago and she said she was sad but felt relieved because she was afraid of what my family would say, im happy she is great but now i feel sad and idk why im feeling like this.Â
