I understand your plight on taking legal action, as for me, I will not go into a court of law and get anymore injustice then I already have. Plus I would have to relive it, and for me there is just too much to tell, and I don't want an audience. I just couldn't do it. I grew up in New York, and have friends in low places keeping an eye on all that needs to be followed.
I took the main person's home, job and anything that brings pleasure away from him and he walks with a tattooed forehead of sorts.
The statue of limitations on flashbacks are two years. Well, since we keep having them, use that as a measuring tool, for a day in the future, that may or may not come, but as a relief that you do not have to do anything right now, especially since that stress in and of itself, causes more flashbacks.
I'm sorry you are in pain, I am not very familiar with the workings of ms. I did do home care for a woman that had it and treated her legs with warmth or just massaged them. Her legs were always cold. She would tell me what she needed each day.
Don't punish yourself over guilt, you did nothing wrong. And obviously just the thoughts of doing anything are making more stress. You need to be there for yourself, and your children.
