Really embarrassing injury?!?!

my friends and me were climbing trees when i fell. it was pretty high and the bony bit above my vulva landed on a really sharp rock (but luckily my actual vulva didnt get hurt, coz it didn't hit anything) and it really hurt and i couldnt walk unsuported and m friends had to half-carry me to my house which wasnt that farr away, we wer in my garden. i still cant stand up and the bruising and swelling is really bad and even my hips are bruised and they didn't even hit anything! it is like the bruise is somehow spreading???? is that normal???? i also feel pain in my lower tummy and lower back, i dont know why. any suggestions of how i can help this, except ice, coz i tried that, but anything touching it it reeeeeeeaaaally sore???? i hav school tomorrow, and i still cant walk, is there any way i might be able to by tomorrow???? even moving my legs is really painful, why is that? ow
