Family in PTSD

We have had a lot of stress around the family and poor communication.

My 13 year old is now often screaming at me, even physically stopping me from moving from one room to another.

She has irrational fears about us not having enough food & becomes really miserable if she hasn’t had food she loves.

Tonight going to netball she screamed at me in the car when I wouldn’t give her my PayPal password saying I wanted to do it myself- “why do you have to make everything so hard – I hate you!” She told me several times she hates me and to go away and she wasn’t going to play netball but then when I said “no netball no pizza” she decided she wanted me to walk her to training but as soon as we were there she told me to leave as she didn’t want me to watch.

She’s also hyper reactive to ANY consequences- why do you hate me, she will say – why are you so mean! and says “I don’t want to be alive, because you make life so miserable “”

I can get through calmly as I don’t take it personally but I am worried the stories she’s repeating in her head.
It seems more and more irrational thinking is taking over!

Is there anything special families and children with PTSD can do when any boundary creates a massive trigger?
