Let me pass on what my OA sponser told me over and over when I was feeling sad, angry, frustrated or felt bad about overeating...she said, "This too shall pass!" Being the humans we are, we make mistakes...they make us feel horrid but these feelings can and will end. Now, forgive and start again! We all deserve that best you know!
OA changed me in a very good way and the 12 steps saved me from myself in more ways then just overeating...I let go of other addictions as well. And it started me on the path of the counseling that I sooo needed when I hit a wall that the 12 steps couldn't help me with.
If you feel the need to go and talk about weight issues, they are good about that. If you need to find recovery by listening and helping others, they are great for that. Google Overeaters Anonymous, there is a website that will give you phone #'s and the where and when of meetings. They don't have all the answers but there are a great support for additive people.
Good luck, honey and reaching out is never the wrong idea!
