I'm so scared for this Wednesday

My parents are divorced and school has been an ongoing issue. My dad agreed to get us into school in my mom's county but he registered us into his school instead and we're supposed to go to school on Wednesday. I'm with my mom this week and she basically told us that we weren't and that we were going to her school instead and she's not taking us to school on Wednesday. I'm really worried about how my dad is going to react because he gets angry quickly and he was excited for us to go to his school. I'm not really sure what to do, I hate the feeling of not being able to do anything. I can't tell my dad because then a whole fight will break out with him and my mom and I if I don't tell him he'll lose trust in me. I asked my mom if I can pretend she never told me and act oblivious to the entire situation and she agreed. I'm not sure what's going to happen and it's scaring me a lot. I'm already scared about having to go to a new school because I'm a total loser dweb that doesn't know how to talk to people and dresses funny.
