Dear anyone

My niece just had baby # two and lost them both to cps. I've been ttc for 4 years to no avail and I'm so mad that people ask me when are you and your husband having kids when are you going to bring home a baby but my niece can have kids and she doesn't want not can take care of them yet I can't get custody because the grandparents want them. How is this my life. I wait month after month in tears feeling worthless feeling like I'm broken with depression caused by my body giving up on me and she was on birth control using condoms and they get pregnant. Why am I not worth it. Why is it not my time. Why can I not have children. Why did my husband give up on me. Why can't I be normal.
