I am really sorry your for your loss but let me give you some advise hon, you had an adoptive mother right . Wasnt she wonderful and took good care of you. You were a gift to her and your bio mother is just that a egg donor not you mom. She made a mistake that she cant live with its not any thing you did. So be happy with who you are any move on you found out what you needed to know.
