I did more than 90 in 90 as I did two a night some nights and two on weekends sometimes. I have been sober 14 months and I have seen plenty of people go out and come in. I have never actually heard anyone snicker, although that doesn't mean it hasn't happened because hey, you have *ssholes everywhere even in AA. But by the far, the majority are glad to see you back trying again. I know for my group we will move heaven and hell to help someone who is HONESTLY seeking to get sober.
Good luck at your meeting. Walk in with your head held high knowing that you are trying to do something about yourself and there is NO shame in that. You are to be commended, not condemned! The past is the past and today is today. You want this thing, go in and grab it with everything you have and don't let go no matter what!
Hugs,
