Emotional Trauma PTSD support

Hi. I am looking for anyone that may have experience with PTSD from emotional trauma. I’d love some personal experience and coping tips as I am in a rough season currently and can’t seem to find lasting resources in my area.

A little of my story is that I was diagnosed with PTSD in 2017 from emotional abuse and trauma from my spouses’ cheating and ongoing sex addiction. I didn’t think much of it till recently. My spouse had since had strokes and I had become full caregiver. I was under the impression they were sober for years as well as brain damaged and when I asked for help for physical and emotional abuse from their Drs, I was told it wasn’t their fault. I discovered they had downloaded a hook up app on our young child’s cell and correctly entered all their info. This was a day after leaving an acute rehab where I had to do all communicating for them. I wasn’t able to get help again as the law is on their side. I had a panic attack last two days and end with me passing out. Since then things have escalated. My child begged for them to be removed and we got one lawyer to take us on. But until a divorce is final I am still legally responsible. Therefore when I have to care for them in any way I tend to still have physical reactions. Any tips to get through triggers you can’t walk away from?

i have been dumped by a lawyer and therapist due to my situation.

Thanks for reading. All input welcome.
