How do u vent..

I just went thru probably the most traumatic experience ever... I mean maybe I should be affected more but I emotionally detached myself from it cuz I've been thru this sh*t before and viewed it as a bystander/observer perceptive as a defense mechanism.. idk like whilst it was happening, I didn't cry or anything, I didn't feel anything. I was analyzing everything, as if I'm not in my body.. observe the observer type shit and simultaneously deescalating everything and therapizing everyone, cuz apparently no one in my household is smart enough to. maybe that's why I kept laughing in the middle of it at the absurdity of the whole... I'm going off on a tangent... My question was that I do journal and I have vented to my myself and god... But idk I feel like I need to tell someone this, but it's traumatizing and I don't want them to get alarmed. Idk
