Discontinue SSI Benefits By Self ? - advise

How Can I Discontinue SSI Benefits Without My Representative Payee's Permission ??

I Have been recieving ssi benefits for several years now for a disability and a family member is my payee. However I have just finished school and I want to discontinue the ssi right away before I even start working.I no longer wish to be on ssi. I was told I have to have my payee's permission and knowledge in order to terminate ssi benefits and that the payee needs to be present with me for the paperwork to be done. I want to know how I can discontinue benefits on my own by myself without my payee's permission since my payee still wishes me to recieve benefits even though I disagree. I was to just start working then the benefits will just stop on it's own time Or to just go through the ticket to work program. However, I would like to just stop benefits all together right now since I no longer feel eligible. How can I do this by myself without my representative payee's permission ?? I am over 18 (20s) and capable of taking care of myself and of working. I reside in the state of california. How can I terminate my ssi benefits by myself without my payee ?
