Mom read my texts on my phone... 10 pts best answer?

ok so my phone took my phone and read some of my txts that i had sent to guys.. they were about sex stuff and NOT good. like i had sent some pics to them (stupid ik but i didnt put my face in it and the guy lives in florida so...) but i havent had sex yet ive just been talking about it. she was pissed and isnt talking to me rite now and took my phone away and grounded me. most times shes a REALLY easygoing parent and i always get wat i want but shes a christian and christians dont do that. im not really one tho.... what do i do?? i want my phone back soo badly and i need it for school sports and stuff too so shes gonna have to give it back eventually. i wrote her a ltter explaining my side of the story and saying i was sorry. when do u think she'll give it back? is there anything i can do? plz dont say give it time cuz i need my phone now!
