Stopping adoption process

Hi mummies, I just birthed my baby girl few days ago on Aug 2021. I had planned for her to go for adoption for the longest time due to disagreements from family and that my boyfriend felt we were unable to provide for her. I have always wanted to keep her but I have no choice but to send my baby girl for adoption. My adoption was through an agency and private - not under MSF. I cried so hard signing the affidavit to give up my child for adoption and was threatened I will be disowned if I kept the child. I have been thinking for a few days and crying nonstop thinking about my newborn. I am thinking if I should just stop the process and get my child back, get disowned and wing it with the support of my boyfriend or just accept my fate and tell myself it's for the better as the adoptive parents will be able to provide for her. I feel bad for the adoptive parents who probably prepared for her arrival and wasting the adoption agent's time.. But I can't stop thinking about her and crying over her. Please advise or give opinions and not be so harsh. #advicepls #pleasehelp #firstbaby
