Elaine, I'm so proud of you for doing this! Many blessings to you.
I'll echo the "one day at a time" suggestion you've already heard and add that you can take it one hour, one minute, or one second at a time, if a whole day seems even too much to handle right now, as it does for many early in recovery. In addition to your meeting at your church, NA may have other meetings in your area and even meetings online that you might like...
I've been clean and sober for a fair amount of time, so I'm very willing to share my experience, strength, and hope about this topic with you, if you ever want to talk - feel free to PM me for my contact info! Big hugs!
