Thank you for sharing your story with us, it sounds like you and your son are going through a lot right now. I imagine it must be really tough to be worried about him so much.
You've mentioned that your son has been seeing a psychologist, I'm wondering if you have been able to talk to anyone too? Going through this can be really traumatic and it's important you look after your own mental wellbeing as well.
It might also be helpful getting in touch with Family Drug Support - they have a free, 24-hour national telephone support line, as well as support groups, education programs and counselling.
Congrats on the new granddaughter on the way! I hope that brings you some joy in the meantime
