What should i do? :(?

About 5 hours ago, my sister dropped a heavy rock on my toe. It started to swell up and bleed and i cant walk or bend my toe and the pain is hell. I showed my mum and she said it's nothing. 3 hours later i asked her if she could take me to hospital but she said no and the hospital is too far for me to go by myself. What should i do? and what do you guys think i have done to my toe? any advise. im 15 by the way. Thanks
