DebC. My heart went out to you when I read your post, I know these feelings too well.
I hope you don’t mind me saying but I’ve had massive help and support from accommodation concern. They have put my son on their Supported Living programme for 6 months. He has moved into one of their houses.
Its given me some space to breathe and to have time away from him and his vile behaviour. Is this something that you too could enquire about? My son gets regular visits and help by having someone to talk about mental health, addiction, budgeting, cleaning and housekeeping. It’s been 2 weeks but it’s been a big help. I just get phonecalls now and I can end the call when he insults me or is aggressive.
Its such a hard life seeing a loved one so unhappy and also being the recipient of their venom x
