I know how you feel.
I'm always overwhelmed after telling someone about my trauma. It feels like I've just made a huge mistake and I'm starting to second-guess myself, think I should never have said anything...
Scared of what the other side might think of me.
It's good you felt comfortable and safe enough to trust your friend, I can imagine it wasn't easy.
We may be afraid at first but once It's over, you might realise it actualy brought you closer.
