Please help 4 week old kitten with poss. broke back?

Ok ok. I know what most of u will say. But I seriously can't get into a vet until monday the closest walkin vet around me isnt within walking distance in fact it 3 towns away. So don't waste you time telling me how shitty I am. Just help me. I have a kitten she's about 4-5 weeks old. She was sleeping under the blankets on my bed and I didn't know so I got on the bed and kinda just fell on my knees and she was under my knees.:( she was like writhing in pain. And she's been sleeping. She's been pooping involuntarily and she can barely hold her head up. But when she's laying down she can move well. She can't walk and she's keeping her feet close to her. I thought it was her back or neck but what's throwing me off is that she is moving her head her back legs and one of her front legs. I feel so helpless please somebody help me. I have no idea what to do.
