Hi
Thank you for posting your story. I am so sorry that you are dealing with all of this as well as caring for your disabled son and not being able to work. It must feel really hard.
I work for a charity called The Icarus Trust which is there to offer support to people who are dealing with the affects of a family member’s addiction. Perhaps you would like to talk with one of our trained and experienced people who would understand what you are going though which might help.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that this is useful Good luck with everything.
