Rainbow, I am a birth mom -- I chose to give my son a better life than he would have had with me. I did it *because* I loved him, not because I didn't! And I can tell you that every birthmom I know grieves for her lost child the rest of her life. It is what caused the larger part of my depression and PTSD.
I love my son with all my heart and I've no doubt your birthmom loves you as well. I hope you find some peace with that.
Love, Candy
