"My beautiful sweet angel," she began in her post. "I have loved you beyond words or description from the moment I felt you in my belly. You have been my joy my heart and all that was ever pure and real in my life. I wish I was with you right now. I wish I was with you. I don’t know how to live without you but I’ll try to go on and spread the love and light that you so made me feel in getting to be your mama," she wrote.
