Good morning- glad you posted.
What's your plan for today? Just today. Sounds like a great time for an AA meeting, and certainly for finding everything possible to do except drink.
You can quit- there are IRL programs (I am a big AA-er and others around here can also vouch for their success with programs like SMART and AVRT, especially on the other side of the pond) and things like the Class of November under SR's Newcomer's Daily Support Threads, and plenty more around here.
Good luck- hope to see you around.
