I’m sorry you’re having so much trouble with your step father. I can’t imagine living in such a confined space with my parents. I can’t even imagine living in that small of a space with anybody at all. Are you able to find ways to get out on your own more? Can you go for hikes or bike rides? Are there things you can do to make life more pleasant for yourself no matter what’s going on around you? I know relationships with parents can be very hard at your age and especially with step parents. Is it possible to talk about some things with them? Can you ask for a family discussion and perhaps bring up some behaviors and issues you would appreciate if they stopped and also be open to listening to their side of things as well? Sometimes this is possible with people and I know sometimes it’s not. In the end, your behavior is all you can ever control. Best of luck to you. I sincerely hope things get better.
