Tanya, just a few suggestions.
Do you attend meetings on line or by telephone? That would be something you could fill in with at night and give you strength. You can find these at oa.org.
Do you have OA literature, if so reading that for 20 minutes might help, if not read it for another 20 and so forth. I learned that from a lady years ago. You can do anything for 20 minutes when you think you can't do it for 24 hours.
Do you have a God Box? Put those foods in the God Box and let your HP have them, He'll know not to eat them.
As far as knowing people at the meeting, I live in a small town of 29000 and it's pretty hard not to know some of the people in the meeting. It is very hard to walk into that first meeting and you might or might not know someone there but you will be very glad you took the walk. I suggest that you go with your HP and give it a try.
As for not wanting people to know you are a COE most of us have thought that and found out once we've been in recovery for awhile all those people we were afraid of knowing already knew and are happy we are getting help.
This is a new hobby I've taken up and love and it occupies my mind and hands and it's called quilling. It's old as the hills I guess but I just am learning about it. I did a google of it on line and found lots of information about it so you might give it a try. It's easy, trust me if I can do it anyone can do it I'm not a crafty person.
Please keep posting and this group will keep supporting. That is what we are here for is to help one another do what we cannot do alone.
hugs
