How can I become my own legal guardian?

Currently my mother Gretchen Lipman has been my legal guardian for the last 7 years. I feel I deserve my human right and opportunity to become my own legal guardian. I want to have and feel like I'm in control of my own life and that my mom doesn't have full control and is no longer my legal guardian any further. I wanna be the one who decides when I can live in my own apartment, the one who decides how to get to and from places, and what jobs and things are best for me. 7 years ago I wouldn't have been in a mentally and emotionally stable place in my life where I could fully be 100 percent confident and believing in this. 7 years later, I am better and stronger emotionally and mentally than I've ever ever been in my entire life. Now I can honestly and truthfully say with full 100 percent confidence and belief that I feel and I know I am finally ready to become my own legal guardian. My attorney is James W Cawley Jr. I need his actual office phone number. Please help me get it.
