What do I do??

I got in a fight at school on Friday and surprisingly the school didn’t tell my parents. But I just got a call from the school wanting to talk to one of my parents. I panicked and pretended to be my momma. The principal knew I had faked being my momma and he said I have detention every day this week and he said he’s gonna call back tonight when my parents will likely be home! I dig myself deep and I don’t know what to do! Please give me advice! My dad is home but I told him that it is just a friend that called. If he knows I lied I will get in even more trouble! So either way, I’m going to be in trouble!😭😭
