Oh my god, that is horrific for a daughter to have to live through. Not knowing what’s happening with you Father… I can’t even begin to understand. I know your Father was getting help, but have you thought about some for yourself? Addiction, no matter what type or level of it, drastically affects the entire family and all are in need of support. There is somewhere you can go to. The Icarus Trust is listening and signposting charity who is here specifically to try and support families who are dealing with addictions. You can contact that on their website http://www.icarustrust.co.uk or email them directly via info@icarustrust.org.
I hope this is of some help and you don’t get that dreaded phone call any time soon.
