I seriously doubt anyone being sent to mental institution over what you said is happening. Fact is, there are more than just yourself going through this right now. I am not sure what the law is where you live, in the states, your conversations with medical/mental health workers are confidential and the Dr can't share details with parents other than treatment plans and what the patient gives permission for. The shrink will try to find ways to help you stay in your current living arrangement and stop self-harming behavior. Best of luck to you, get some help so you can be happy
