Understand AI use at MyPTSD: all AI use is explained in our AI help page. AI use is by choice here. It exists if you want it, but does nothing unless you choose to use it.
You have every right to be angry that someone shot you and murdered your sister. However, the problem with PTSD is the fight response and the corresponding anger can become the go to response for things that don't warrant that type of response. Personally, I felt like there was a switch that was stuck.
I found the information here helped me to understand what was going on and to make the changes necessary to break the cycle. For me anger was a response for a lot of things, but especially fear and the fear had spread to things that before I wouldn't even find frightening. I hope you find this site beneficial to your own healing.
