Keep your focus on yourself at this time. I went through a similar situation with a home care person who I caught abusing my mother when she was dying of cancer. To take the sight off of herself, she called the police accusing me of abusing my Mom. Nothing came from that. It was a nightmare & the scariest time of my life. Realized I had to protect my Mom & had no support around me, just people telling me that things like that don't happen to people like my Mom.
I so understand the feeling you are going through & that PTSD in process is the worst feeling of all. My pdoc wasn't much help at the time either. I am so glad that you do have supportive people around you & that you have your line up of legal help. It's difficult to stay strong through experiences like this, but it's possible. I experienced depersonalization after the trauma which farther scared me not understanding what was happening.......that was 11 years ago.....& I am mostly healed now over the last few years. It takes time & a lot of self care.....my heart goes out to what you are going through
