i am 16 and my mom grounded me for 3 months (until next report cards come home) because i had a 76 in u.s. history. she told me i would be grounded for 3 months, then i talked to her down to 1 week. i said somethnig to her about it and she called me a "liar" and said "i am putting words in her mouth" about me only being grounded for a week. it is very hard to live with my mom beng like this and i have considered leaving home many times. PLEASE PLEASE PLEASE help me
