Am I a Mom?

I’m struggling so much with my TFMR. I feel like a mother that lost her son. But I didn’t carry to term, give birth, or hold my baby. I feel like an imposter imposing on mother’s that lost their birthed children. I don’t know what my role is in grieving. Part of me feels like I don’t deserve to mourn as I made the choice I felt I had to make. Does anyone else feel this way? This was my first pregnancy.
