I think Chaoticsymphony is right it does sound like hypervigilance - something which i myself suffer from so i comepletely understand where your coming from. I don't know how old you are but i found the only way i could resolve the crumbling relationship i had with my mum was to move out. I got given a place in a youth housing scheme because i was suffering from abuse in my home at the time and i wasn't considered safe. From there they helped me find a flat i love and im really happy here. I don't know where you live or if this would be an option for you but im from the UK so if you are too i would check it out. How about going to stay with some other relatives for a bit? Could you go stay with an aunt or a grandparent once a week? You could agree to do some chores for them or help them out with some errands in return for their hospitality and it might help you and your family get the breathing space they need. Good luck sweetie
