I just had the BIGGEST fight with my mom ever...?

[Fairytale Princesa]

Okay so, today i wanted to clean my room & bake a cake, but my mom said "no it's sunday you need to rest" so i said "kay" i sat around in my pj's all day and played a game. Then when it was bed time, I went in my room and sat on my bed playing the game, instead of going to bed. Then around 2:20 am I decided I'd clean my room. So i cleaned it, probably making alot of noise and when my mom started yelling at me to turn my light off and go to bed, i started arguing with her saying i wasn't doing anything (which i lied) and then when i finished and got into bed, she continued yelling at me, so i told her to shut up and let me go to bed. That didn't work because again she brought my christianity up again. Then i asked her why she took my car keys and she then replies that she read a note between me & my boyfriend... so i went off. (i dont like for her to go through my personal notes). She gets up and goes to the bathroom so i decide to confront her (which i shouldn't have done) and we started getting into the fight there. Not physically but me mostly yelling. At the end i told her she was too stubborn to die. And then she threatened to call this lawyer guy (cause i'm adopted) and tell him what's going on.. which idk why.. Then after that, i sat in front of her, calm as can be and spent about 5 or 6 minutes giving her the best apology i knew how and i told her it was my fault, and i was only thinking of myself, and blah blah blah, and she wouldn't look at me the entire time. She wont accept my apology and she's really upset. I honestly wanna make it better not so i can go out with my friends tomorrow because i don't care about that any more. I CARE about making her happy. I mean, she does things for me... why shouldn't i for her?! NOW! I don't know what to do because it's 4 in the morning and we're both locked in our rooms away from each other. I really wanna make things right so things wont be tense between us tomorrow. What can I do to make things better?! PLEASE HELP!!
And might i add, right now she's in her room crying because of what i said. SO something GOOD needs to happen Dx
