Adore79, you have a legal right to choose your advocates.
I was a conservator/guardian for a mentally ill brother for 4 years until I turned my task over to another agency bacause I felt I could not fulfill that task appropriately and in my brother's best interest.
Just for your information: if you are the recipient of any funds due to mental illness or disability: your check cannot legally "just disappear" to anybody.
You have your rights and you have rights to request not only legal rights, but legal representation.
PM me for more information, because anyone who recieves your checks has legal obligations to handle that money in your best interests.
