Decide the boundary first
Mind advises supporters to be realistic about what they can do, take breaks and share the role with other people. A boundary may concern:
- which calls you can answer and at what times
- money you will not lend or manage
- behaviour you will leave the room or house for
- tasks that need to be shared
- when you will contact professional or emergency help

Say what you will do
Keep the wording short. Avoid arguing about whether the boundary is deserved.
Keep urgent safety separate
A boundary does not mean ignoring an immediate danger. If someone's life is at risk or you cannot keep anyone safe, call 999 or go to A&E. For urgent mental-health help that is not an immediate emergency, use the nation-specific urgent routes.

If the boundary is ignored
Repeat it once, then follow the action you stated. If you regularly feel frightened, controlled or threatened, use specialist domestic-abuse support. Mental illness does not make abuse acceptable.
If you are frightened of them, not just worried about them
Call the National Domestic Abuse Helpline on 0808 2000 247, the Men's Advice Line on 0808 801 0327, or Galop's LGBT+ helpline. If you are in immediate danger, call 999.
