<human>: Can you succinctly summarize the text in 1-3 sentences?

A few years back my family was going to the states to go shopping, my Aunt lives beside us and she said she would look after me if I needed anything. My cousin and I decided to go quadding and for some reason I decided to sit backwards on my quad, going full speed, and try to drive. I lasted about 10 seconds and then I accidentally jerked the handle bars to the right. I ended up being thrown in front of the quad and as I was falling/flopping around on the ground, I saw the quad tire coming straight for my head. I think I was knocked out because I don't remember anything after that. Magically I appeared back on my quad and my leg and chest were in a lot of pain. We were only about 500ft from my cousins house, so we went there. I told her what happened and she didn't seem concerned. I asked if we could go to the hospital and she said "no, you're fine". I was extremely pissed off so I started walking out of the house and was really dizzy and fell to the ground, at this point I am terrified and beg to go to the hospital, again she says "no, you're fine". I was INSANELY pissed off now, and the dizziness went away so I stormed out of the house and went home. I sat on my couch waiting for my family to get home, and by now I can't move because my ribs were badly bruised.

The funniest part was that my cousin flipped his quad a few months previous to this and he was driving a tiny 80cc going 1/3 of the speed and his mom rushed him to the hospital. He had NO signs of being injured and everything turned out to be fine with him. I ended up having all bruised ribs and my right leg was all bruised and swollen.

Needless to say, I don't trust her anymore, and she can fuck right off.
<bot>: Flipped my quad, was in pain and my aunt who was looking after me didn't take me to the hospital.
