What would you have done in a situation like this?

The other day in PE, everyone was igned in groups for a relay race. Of course, I was the slowest out of my whole group, which happened to be full of over-excited, win obsessed boys. Whenever it was my turn to go, they would yell & scream, "GO!! RUN FASTER, FASTER, FASTER! God, stop being so slow!" I even told them ahead of time that I was slow & that they need to be patient with me. Well, I tried to run as fast as I could so I wouldn't have to listen to them b**ch at me later & it resulted in me wiping out twice. The first time, I fell on my back (which isn't good at all considering my scoliosis). I sucked it up & kept going. The second time is when I was really hurt... I fell forward & landed on my hip whilst skidding across the floor & punching myself in the ribcage in an attempt to catch myself (which obviously failed). It knocked the wind out of me & I was just laying on the floor. What really pissed me, my family, & my friends off is that none of my team or cl mates came to help me while I was laying on the ground, hurt & unable to breath. Instead they started yelling at me calling me slow & worthless. By the time I started to breath again, I looked at my hip, which had a giant purple, puffy skid on it that was bleeding. Some of you may ask, "Where was your teacher when all of this was going on?" ...He wasn't paying attention. I didn't even bother telling him, he's a gym obsessed freak. The only answer he would've given me was, "You're fine.". Today, the day after my incident, I'm very sore all over my body. My ribs, spine, & left hip especially. d: I was about ready to tell them to f**k off for yelling at me instead of helping me. So what would you have done if you were in my position?
