Help me during my healing process

Hello just some background before getting into my incident I must say I am 17 with only one parent which she just started a new job , no insurance so any help would be very appreciated from us both ! The school said they are not responsible even though an incident which we never signed a waiver for happened in one of their programs at east central high school I’m in a fire fighter program , today 11/16 we were doing an outside activity which included a fire fighter hose clamp made of metal ! When I pulled up the pressure of the water in the hose completely shot up the handle which then went into my jaw piercing a hole under my chin as well as also left a good sized bruise , after the fact of getting hit by such blunt force and finally able to get out of the state I was in I noticed I had 5 broken teeth ! I sat down and was dizzy as well as almost blacked out twice , after the fact I went to the emergency room where I got stitches as well as a X-ray that shows my jaw fractured , after I was done we came to the dentist which where they pulled off the hanging parts of my teeth , Still more to go but I’m starting this go fund me in the midst of it for any help we can get , I still need to go see a specialist for my fractured jaw .
