Yesterday i screwed up big time with my mom

and now she is like SUPER moddy

with me how can i make it up?

What happen was i hurt my leg a week ago

and i needed to go and get my soccer uniform and she went and got it for me but my coach wasn't there so she couldn't get it so than a while later she takes ME to pick it up but my leg was like majorly hurting so i told her if she can PLEASE get down and get it for me and she said NO so i got all mad.

I kind of feel bad. But did i really do something bad??
How can i say sorry/make it up
