E.T.
Unless your parental rights were terminated, you have a legal right to see your daughter. He cannot keep her from you - this is illegal. I do not know if you are financially able to afford a lawyer - but it sounds like you need consult one. Just because he was awarded custody does not mean he can tell you that you cannot see her. If you cannot afford a lawyer - there are many programs that offer legal aid to people that are under a certain income bracket. Here is a website that may be helpful to you: http://www.legal-aid.org/en/home.aspx
Good luck - and I will be keeping my fingers and toes crossed for you and your daughter. I cannot imagine the pain you must be feeling - I would lose my mind if I could not see my children. Hang in there and fight for her.
