Oh SPF I really do feel for you. I understand what you are going through as I have abuse off my DS too and have thrown him out before now. The stress is unbelievable. You have done remarkably well though in the circumstances of probably feeling like it's all a bad dream. Your mind is probably in a fog and you are just working on impulse now. I do hope you are getting some rest as I type this.
The trouble with trying to find somewhere new is that you will have to have all the stress that comes with moving, finding somewhere that is for disabled or setting it up for your use as a disabled person and costs involved. It is more than unfair for your DD to put you in this position. Will she calm down over the weekend, do you think or get worse?
Did you manage to change the lock? That is important. Did your doctor give you any medication for helping you to sleep or to ease your anxiety? Did you ask for any?
When my DS had caused trouble, I have involved the police. I have got it noted so that if it did get worse they would have records of him doing it before. About three times now in total but enough for me to be stressed about. It is a taboo subject, being abused off our own children. Loads is now done for abused children but not much out there for parents who are being abused by their own children, of which there must be plenty.
Keep posting, get some energy rich food in (have it delivered), look after yourself, take deep breaths, and remember you are the parent, you do not deserve this treatment. Stay focused on what you need to do to make your life safer, less stressed, happier and peaceful without all this threatening behaviour. Write it down, lists of what you can do, how you are feeling hour by hour if need be, scream into a pillow, anything to release the anxiety build up and stop it eating away inside of you. I will be doing all this in 5 weeks when my DS leaves home, get my stress levels back down. Take care love, Xxx
