I am so sorry. Feeling your pain.
I know that sometimes there is nothing rational about a fear, but still it is there.
Do you have anything you can use to embank these emotions? Is there anyone you can talk to?
What are your strenghts?
Sounds to me like you identify strongly with the victim role in the police scenario. Did something like that happen to you before? My suggestion would be to take control to make things better and empower yourself - not surrender. Talk about it. Talk about your emotions and the events which triggered them. There is room for change in the future, and you don't have to stay where you are. (Thinking like that often helps me when I feel stuck)

I don't know anything about your situation, but I hope you will find a way to cope with this. Lots of comfort and support to you!
