Checking yourself in doesn't always mean that you can check yourself out. Sometimes there's a minimum stay time. That can be changed by the doctors though if they feel that you are ready to go home. But they can also keep you as long as they deem necessary if they feel that you are a danger to yourself or others. That may not be the case where you are. Those are just my experiences with the hospital. I'm sorry that your folks won't listen to you. I hope things get better. Good luck and keep us posted.
