Miscarriage & keeping it to yourself

Emily • 20•momma to Oliver•wifey to Derek
I had a miscarriage about a month ago & I've kept it to myself. My mom doesn't know I'm sexually active & I just got clean from drug use. I feel so alone & I want to cry every time I walk past a baby isle or see a mom & her little one. I want to try to conceive again but my current SO already has 4 kids. I'm just sad. Does anyone have any stories of getting less sad?
