How to release trauma whilst experiencing it?

I've spoken about this before on Reddit but I am currently homeless due to DV, whilst I am in as stable of an environment as possible I keep recieveing texts from my abuser.

I am working with the police plus multiple other organisations but they are slow, it feels like whilst I understand the manipulation tactics my body doesn't.

Every time I get close to grieving the loss of my entire family, my abuser messages something and it leaves me shaking.

I have to not block her, it is important for the police investigation that I continue to screenshot but my C-PTSD keeps being re-triggered.

I will be in this for months and months more so I really need advice as right now the light at the end of the tunnel cant be seen or predicted.

How do I release the tension, the pain, the emotions each time and get to some form of equilibrium in my life?
