Hi Detonator from another UK based alcoholic - welcome to SoberRecovery.
It might be worth chatting to your GP anad seeing if they can refer you to any local programmes. Also, being in London there will be an abundance of AA meetings that you could choose from. Many people do 90 meetings in 90 days to kickstart their sobriety. That wasn't an option for me after the first couple of weeks when I was on holiday from work, but even 2 meetings a week makes a huge difference to how I cope with sobriety. You can do a postcode search to find local meetings.
Find a Meeting | AA Meetings | Alcoholics Anonymous (Great Britain) Ltd or call the hotline and they'll get someone from your local area to give you a call.
You sound like you have reached a level of acceptance that is vital for embarking on the road to recovery. This is the first step. Good luck
