Hi Gill … My heart goes out to you it must be extremely difficult for you living like this. My son lives at home and smokes a lot of weed and has done for s couple of years . He to can get verbally aggressive and although has never hit any of us he smashes things round the house. I wish I could offer you advice that would help but I can’t I only know that my life got better when I contacted a family support worker and started to put boundaries in place and I stick to them . Sometimes it works and sometimes it doesn’t but I keep trying . You must feel very frightened and alone . Please don’t blame yourself or suffer in silence speak to someone and get support for you and the rest of your family . Sending you big hugs strength and courage xxx
