I'm pre-op as well and I feel like I have been working on coping mechanisms for quite a few years now as I became more and more aware of how I am a sugar addict/compulsive overeater.
I don't go to OA now but I have gone many times in past years. Friends from OA taught me how to use things other than food to help me cope like:
Calling a friend, going for a walk, journal, praying/meditation, quilting. I would say journaling has been my biggest help. When I didn't know what to write I either just put my pen to paper and kept writing anything for 15 minutes. Even if I wrote the same word &uck 1000 times I always felt better afterword. You could write a gratitude list or.......write about an issue that's been bothering you. You can burn it afterwords. No one has to see it.
Another thing is to write a letter to yourself but do it from the perspective of a good friend. In other words a good friend would be kind, forgiving, loving and caring. She/he would want to take care of you.
Best wishes on your journey.
