You should know in case you need it:
In a mental health crisis, you have options. The very best is to get your child to the ER for an emergency psychiatric evaluation.
If you cannot safely get the child to the ER yourself, you can call the Mobile Mental Health Crisis Team or an ambulance and explain that your child is in an uncontrolled mental health crisis. This is a better option than calling the police.
Here are some resources (first link includes the phone numbers for the mobile mental health crisis teams in MD):

You are not alone. Call for help.
