Help, I think I really hurt myself?

So I have this hobby where i make knives. It sounds dangerous i know. Anyway, i make medieval daggers and then sell them to people. i was making this bronze dagger in my backyard forge, when my hand slipped. i wasn't wearing gloves and i burned my hand on the red hot metal. I screamed and fell backwards, and started to roll down the hill in backyard (there arent any fences). I kept rolling and i couldnt stop my self. I rolled into traffic, almost getting hit by cars, and slammed into the curb. I got up, and was dizzy and disoriented. I tripped and fell into the pond right next to the curb. (The water felt good on my burn lol) Its a pond where they have people rent paddleboats and stuff. I tried to swim to the surface but was stuck under a boat. I passed out cause i couldnt breathe. I awoke in the hospital, but since i cant pay for that sh** i tore out of my life support and ran back home. When i got there i tripped down the stairs... HELP IM REALLY HURT HOW DO I TREAT EACH OF MY INJURIES?
