tell me about it, my mom is the same way. She loves me and i know it, which is great but a little freedom would be good too. If your mom is the kind that you can sit down with and talk about anything (which mine can be sometimes) then sit down with her and tell her that you are 17 now and since you are pretty good i dont see why she wouldnt be okay with it. being responsible goes a long way. And the whole thing with your biological mom could have alot to do with it. Shes scared for you, she really loves you and doesnt want to see you hurt the way your bio mom did. which is understandable, just reassure her. make sure shes okay and that she understands that you are growing up.
