Hi Chowebella,
I sounds like you are being totally supportive to your mum and it is hard for you to cope with the affects of her drinking and the way its making you feel. I was wondering if you could do with any support for yourself to help get you through what is a very hard time. The Icarus Trust is a charity that supports people like yourself who are having to cope with a loved one’s addiction. We offer a free service called ‘Family Friends.’ These are experienced trained volunteers who you could be put in touch with. They would understand what you are dealing with, and talking to one of them might help you to make sense of how you are feeling and not to feel quite so overwhelmed.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I do hope that you can get some support and things start to improve for you. Good luck.
