Coming back with a thought or two for you
Therapists have chosen their vocation, trained in it, and have a support and supervision system to help them with the stuff that they will hear from their clients, and for them to be able to help rather than re-traumatise their clients.
Supporters do not have any of those resources available to them, and they are deeply emotionally involved with their loved one.
If your loved one is hiding their feelings,
Then those feelings are probably not safe for them to go anywhere near
They're probably not safe for you either. You do not have training or support.
You can easily sit in your chair and watch unrealistic faked deaths, rapes, injuries and whatevers on TV night after night - because you have no skin in the game. It is very different if it is someone who you care about, describing the real thing. That is if they can even put it into words because trauma flashbacks shut down the speech centre of the brain.
If you do hear that stuff, it can stay with you for a very long time, weeks, months, sometimes even longer (how do I know that?).
Re-traumatization for the person who suffered the trauma and vicarious trauma for the person who hears or reads about it are real. please be careful.
Co-dependency and all of the enabling and passive aggressive behaviours that go along with it are real too, They're very ugly and they are damaging to both people.
please look after yourself first, and respect your loved one's boundaries and limits.
