What should I do to make it up to my mom?

My brother stepped on my face because I tried to turn down his volume on his game because i couldnt hear my movie, and it left marks on my face. My mom punished him harshly trying to defend me, and my brother said he hated her which really hurt her feelings. Then my mom accused me of saying i hated her last night (which i didnt) and now she wont talk to me OR him. what should i do to make it up for her? please leave your email on your sources so i can reply to you if u need more information. this happened about 1 hour ago and ive been trying to make a card for her but it turned out poorly. ive tried making a sorry poem but that turned out a mess. what should i do? any help?!
