Thanks for posting. It was so very sad reading the heart breaking story of your dad’s situation.
I work for a charity called The Icarus Trust that offers support to the friends and families of people with addictive behaviours. If you feel it would help you to talk to one of our experienced trained volunteers please get in touch.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
All the best and good luck with the band!
