Hi,
I’m sorry to read how you feel about your friend’s drinking. I can see that this is really worrying and upsetting for you.
Please contact The Icarus Trust if you think you would like some help. We are a charity that offers support to people who are dealing with the addictive behaviour of a close friend or family member. One of our trained and experienced people would talk with you and maybe help you to know what to do next and cope with the emotions that you are feeling.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope this helps. Good luck.
