Hello Sarah
I am not familiar with support in Surrey but on a quick googlecsearch found this link…could be helpful…
Have you looked into meetings in your area or online?
Also - check out this message - great links to alcohol support.
Wishing you the best in your journey 
Edit- also, im current reading book "quit like a woman "… im finding it super helpful. Taking me some time to read as each page is filled with so much insight im finding myself re reading pages to soak in the entire message.
