It IS a bit overwhelming when we realize what we've done (the using and whatever came with that), what we've missed and what we need to catch up/make up for. However, it can't all be done in a day..not even a week or two. I do remember thinking there was too much to think about, to handle.
This is where, whether you go to meetings or not, it's really important to try to stop and think "what can I do, right this minute". A lot of times, there is not much you can..maybe make a phone call, or check something out on the computer, but for most of us, it's okay to call someone, go take a walk, journal..something that clears your head a bit.
I've got almost 3 years clean, and there are still days when I'm overwhelmed and have to stop, breathe, and say "okay, what can I do about it RIGHT THIS MINUTE?"
Hugs and prayers!
