Have to contradict another poster i'm afraid - there's no point in going into recovery telling lies (no idea why you'd start out at your first meeting lying about being sober for 3months as PP suggested). Sure be cautious about who you give your number to and only share what you feel comfortable to share as you feel comfortable to do so.
However having phone numbers is a life saver to many in early sobriety. Picking up the phone can literally save your life and it's not easy if you've gotten used to isolating and hiding and being so bogged down in shame that you can't reach out to or be honest with anyone. So please do disregard that advice.
I was warned to remember there are some very sick people in AA.
Best advice stick with the winners, get in the middle of the bed, keep coming back and remember it is just one day at a time. Get the Just for Today card and stick it on the wall by the loo or your bedside.
I'm not anywhere near perfect with practising my programme consistently but even reading that card can help me focus. I particularly like the reminders to stay in the present and not try to 'tackle my whole life problem'.
One friend is obsessed with saying she just lives her life trying to do the next right thing. So if she gets lost in thinking or negativity or anything destructive for her she can recalibrate by thinking what's the next right thing? Which may be as simple as ah yes, I was going to make a healthy dinner for myself or hmm I''ll get on and put that washing on. Whatever!
Take it easy on yourself and take life slow is my best advice for early sobriety. There is a lot of facing things we've done in the past because it all starts to hit us how much we've lost or caused or hurt ourselves or others. The object isn't to beat yourself up though and there's plenty of time to work through all that. There is also a lot of new emotions and states to deal with that previously we didn't have to work through because the answer would have been to reach for a drink.
Go easy, be gentle on yourself, pick up the phone. (I was and still am nearly two years later pretty awful at that last one!)
