Hi blue…I choked back the tears when i read this and fully understand what your going through…luckily for me not to the same level of violence although my son has subjected others to that…
I had to be hard with my son I have his older brother living at home and also his toddler brother..He too has stole, lied and bled me dry of money and been abusive when he dont his own way.
Sometimes you have to come to realise that you can only do so much and that if they wont accept help then they are not ready to change their ways, which in turn means you have to stand back.
You have a life also and dont have to be part of his chosen one…I know its difficult when you love someone so dearly but it has to be their choice to change.
I feel for you all and your parents they are clearly being manipulated because they are frightened of him….I think perhaps it may be time for you to sit down with your parents and agree on a plan to end this violence because that is extremely unacceptable…You may need to consider involving the police..please dont let this level of threats and violence to continue…please get some help xxx
