i failed - im certain that i had passed out, but my rope slipped from my anchor point and i woke up on the floor.
what i remember enduring was not painful - i just felt some light pressure in the front of my forehead, but it was not uncomfortable - i have a bruised neck from this attempt, but no lasting pain.
thankyou everyone for your well wishes <3 this is a learning experience - now i know for next time to secure my rope to the anchor point better.
