Hi Jane123, welcome to the forum. Everyone here has a loved one with addictions and also some people in recovery offering support and advice.
Thank you for sharing your story. I’m sorry to read that your son’s addiction to weed is affecting his mental health. It’s very frustrating and sad as a mother to watch addiction taking over your son’s life.
The thing is that you cannot really do anything until they themselves realise they have a problem and want support. Then you have NA, CA or AA fellowship groups to join. From then , the work the 12 steps, get a sponsor meet others in similar situations.
You need to look after your own health and well-being. If you go to the homepage and look at Share Your Story heading. Scroll back and read the Theresa thread. There are several of us mums with sons with addictions who all support and help each other. You’ll realise that you’re not alone.
Keep posting at let us know how you’re doing.
Take care
