shimmery, there’s a couple comments I could make.
First, become as independant as you can. It does work. Get your own alarm clock and wake up to it. Hold yourself responsible for your life. Do your own laundry. Cook your own food. Any of the above. This does a few things, first it makes it so that other people can’t control your own stuff. If you clean your own clothes, your step mom can’t stain them. They can still get stained, but you will have to take that responsibility. You can still be late for school. but its on your shoulders. Its a sense of power and fulfillment once you get it right. Independance feels good.
Secondly, Get an agreement in the house as to what your chores are and when you need to have them done. I was BUSY in high school. I took 16 credits at the University as well as high school classes, plus theatre, choir, yearbook, Model UN, newspaper, and swim team. I worked weekends. I partied Friday and Saturday nights. I could usually total my sleep for three days on my fingers. Naps were my lifesblood, ten minutes on the bus to the magnet school got me through to third hour. Wild days. My mom understood this and gave me assignments on a weekly basis. We’d talk them over.
“Do you think you can cook dinner on Tuesday night and clean the bacement by Sunday morning this week?”
“Yea, I can manage that.”
We got along fine. On my busier weeks, my mom adjusted what I neede to get done at home. When I had time, I did more. My father did not have this understanding. My relationship with my father suffered horribly. (I ejected him from my life thorughout high school. “You may be my father, but I’ll be damned if I let you be my parent.” As adults we’ve ironed things out, but I still don’t see him as a parental figure.)
For your own happiness, iron this stuff out with your stepmom. Get a chore list and deadlines. If its more than you can do (and be reasonable here, put those time management skills to use.) then negotiate it down. be calm, be responsible, be together. Then do what you said you would do. No excuses. If you said that the stairs would be vacuumed before you go out Friday night, make sure it happens, even if you are dragging the vacuum out in yoru party clothes.
Beyond that, don’t let anyone else’s deficiencies bring you down. So she’s a witch, so what? You have places to go, people to see, things to do, and happiness to feel. Do what you have to do, do it well, and get on with your life.
