Sorry............................. This is a no brainer! Someone screams for help in the middle of the night YOU CALL 911 !
I don't mean to be mean, but it SHOULD sit heavy on your mind. You have suffered abuse? you know what she was feeling. You won't get any sympathy on this one. They never have to know who called the police. Depression and Agoraphobia is NOT an excuse. I feel for you since I also suffer from it on and off, but ya know what...............I was able to CALL 911 if I had to. Get on some medication, they have plenty that work wonders for that condition. There aren't to many MEDs for abuse. INTERVENTION! If it happens again remember CRY FOR HELP=CALL 911! No thinking to it.
