Hi Skeldo,
Its very sad to read your post and hear how long you’ve had to deal with your mum’s drinking. It’s not surprising to hear that it’s affecting you badly. Maybe you would like to talk with someone who would understand what you’re having to live with.
I work for a charity that gives support to people like you, who are living with a family member who has addictive behaviours. At The Icarus Trust we have a team of trained and experienced people who, if you got in touch, would listen to you and maybe help you to see the way ahead.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
Good luck with everything.
