Conflict and anxiety

Does anyone deal with similar issues? I have a huge anxiety around conflicts. Until tgere is no conflict- I'm fine. Once there is one- I get so obsessed, often over a injustice,  but I also fear being put in jail or killed as a result of tge conflict. Even if it's nothing really that big. I know, that this is my anxiety. But the awareness does not help much. Now I have a problem at work, because there is some stock missing but it exists in the system. I controlled that and I filled the shelf. I told my manager that it was there and everything was correct and I filled shelf and I have no idea how it disappeared. I also wonder why they keep me accountable for items that were delivered a month ago. And there was a big theft in our company,  one lady stole over 20.000 euro, so now they controll everything and everyone as if we were all thief's. As a result I fear being accused of stealing something and facing awful consequences when in reality I didn't touch anything. Its just a recent example of my anxiety. I had already fears of being killed before. It's always my brain creating some dramatic scenario. My meds help against that - at least I'm not crying and banging my head off of a wall (which I did in the past in such situations) but still it's sitting inside my head. 

Does anyone deal with something similar? Is there any better way of coping? My therapist says its my anxiety. I know, but its still there.

I hope that the items will be found. Communication in my company us a big problem,  so it's pretty possible,  that someone moved it somewhere else and didn't inform about it.
