Take a deep breath. No future tripping.
Backup plan, meaning 911, essential, don't hesitate to make the call.
No expectations of good or bad.
No power struggle, waste of time, no one is really in control in any situation that can turn volatile or chaotic.
You are there for a reason, get in, get out.
I will keep good thoughts.
Try not to drive yourself to nuts, before you even get there.
Hugs.
