United States
Mentally competent patients have a general right to refuse medical treatment.[74][75][76]
All states in the U.S. allow for some form of involuntary treatment for mental illness or erratic behavior for short periods of time under emergency conditions, although criteria vary.
So to force you as a person not in an acut emergency status is illegal and you have the right to deny. On the other hand your dependent from your mother, like Ryan said, but she and the doctors haven’t the right to force you.
