Oh no! My parakeet/budgie is hurt! Urgent!

[chickadee423]

Ok, when i came home today my parakeet was severely hurt. I do not have the funds to take her to a vet. Her leg is black/purple and is completely lifeless, around the top of the leg it is bloody and a little fleshy. She will eat and drink just a little from my hand, but wont go to bowls. I dont think she can move her leg at all, its just floppy.
Please help i really dont want her to die! I cleaned it a little with peroxide and qtips.
