The value in therapy is valuing the space of being seen and co-regulated by your therapist.
Not being saved
Not having them do the work for you
But in order to value that, you have to be present in the session with your feelings and have them see, hold, understand them.
I'm not saying you shouldn't go to therapy if you have CPTSD, it's just you'll feel like you won't get the most out of it. Which you won't.
Think about it, if you're at ROCK BOTTOM, TRAUMATIZED, FROZEN, FIGHT OR FLIGHT MODE. WTH is talking to a therapist and them holding space for you going to do? At best make you more conscious but hasn't changed your physiological health at all.
I think therapy is helpful, but not everyone is in a state that is optimal to experience therapy as helpful.
Ironically, people go to therapy because they're in a bad position in life but it's ironic because if you're in too bad a position in life it won't be as helpful.
