All the police, EMTs, etc were the ones treating me like a criminal
My relatives were very supportive. My aunt who lost her husband to cancer flew out here to spend a few days with me for support and my mother came too.
They did you wrong. They may have misinterpreted your state of shock. I would want an apology from them. Go up the chain as you can until you get it.
I do have one piece of advice, because I know how traumatic it can be to lose a loved one. Be sure to live a life, because should the day come when you are reunited, she will want to hear everything you did when she was gone. It would probably kill her if she learned that her death took you with her as well.
I had that experience with somebody. His brother died saving lives and he effectively died when his brother died. I told him that.
