You really need to talk to your Guidance Counselor to get some support. Talk to them about everything, and esp. how yuo email teachers for help but don’t get it…that you need help this way to
Also talk to your teachers and ask if they could check their emails for questions…that you get punished for being tardy and can’t get help after/before school.
In my experience, super controlling parents who say they will kick you out absolutely will not kick you out. They want to keep control over you. They use the threat to control you.
Imagine what would happen if you said “If you are going to throw me out, I will need to start saving money so the going rate for a waitress is $9/hr.” or if you said “I will let everyone know you kicked out your honor student daughter and won’t send her to college.”
Do know that helping out in a restaurant is an EC.
What I would suggest is to plan how to get out of their control. Act like they aren’t going to kick you out. Put that worry out of your mind. Try to reduce the tardies. Keep studying.
