I am sorry that your mom is acting like this towards you. I know we have all probably been there before. We have all been at the point when it's time for parents to "let go" so-to-speak and the parents just can't let go for some reason. I think maybe you should sit down and talk to your parents and find out what the problem is. Usually, as it is with my parents, there were some communication wires that got crossed or they felt like dreaming something up or someone told them something and didn't get all of the information or got incorrect information.

I think the final solution should just be talking with them and get things straight in their heads. To me, you seem to be a responsible adult paying her own bills, making her own decisions, etc.
