Still struggling with impostor syndrome after my third (but by far most beneficial) meeting

I originally got sober and planned on staying that way on Saturday. I went to my first AA meeting ever Monday night, felt welcome and uplifted, and it was great. Tuesday night's meeting (at a different church) was good too, but I'm sad to say I relapsed that night and fell asleep drunk. I woke up today (Wednesday, though you may be reading this in a time zone ahead of me) feeling shitty emotionally but physically okay. Thought I could get through work okay without a sip or two of Jack Daniels. I couldn't. I had a few sips around noon on my lunch break. But I still had a plan to get to another meeting tonight.

And so I did and it was by far my favorite I've been to. After being warmly welcomed as the unfamiliar face I was and the older people in the group coming over to welcome me, they went a step further and there were about 10 people who put their names and phone numbers on a pamphlet and gave to me. To call them if the temptation of drinking comes back. I was speechless. No one had ever been this helpful towards me about anything.

But the reason for my title is because, even though I shared the basics of my struggles (sipping on whiskey during work, and drinking in the evenings until I fell asleep), I still felt like I didn't belong. The guy behind me looked like he literally just came out of a stupor and was hardly awake (but was there, so I guess it counts for something). And the other people sharing their stories about going on bender after bender, the DUIs some of them got, what rehab was like, etc...the imposter syndrome weighed more and more. "I don't belong here" I kept thinking. I could control myself in public if I drank with family. I’ve never driven drunk either. It's only when I'm home in my room, lonely or stressed, that the urge really arises. I'm tame compared to other people whose lives were ruined.

Sorry if this doesn't belong here. I'm just kind of venting. I do want to try and stop drinking just to do it. I'm a lazy s.o.b. who can't see anything through once I start. Maybe sobriety will be something to work for, idk.
