I myself blog about my trauma in a sealed/private/free blog.

I am in the unique sitation were my tramatic abuse was witnessed by an outside source. This person also received their own amount of trauma too, but nothing compared. This person is very strong-willed however, is also a couple decades older than me. We would (several times a day) discuss the latest (it was ongoing abuse for almost two years) to a point it was theraputic, but then they themselves would talk down to me, also have strong points of view on how next to proceed, etc. (especially after I started retreating as it was really making me ill) it ended up being more of a psychic vampire type situation. Massive energy drain. Not only am I dealing with an extremely abusive situation, but also being drained and somewhat abused by a witness. Too much.

Talking can often times back-fire outside of a safe and professional type setting.

I would recommend writing details of your situation down in a safe place where it can't be found, and only sharing with professionals whose job it is to help you heal. Stay safe everyone.
