I too had some eating disorder issues as a young adult. I saw a nurse for a while in college and she helped me by keeping a food journal. In this journal I would write down everything I ate during the day, why, and my feelings. It helped me to recognize patterns of eating when I was depressed or stressed, then feeling guilty or upset about it or perhaps what I ate. I also recorded all my purging episodes. Having to face it and writing everything down really helped with recoving. I'm guessing that since you have been struggling with this for years, you may have done this at one time and might want to consider trying it again.
I also understand how isolating it can feel sometimes to be a SAHM. I am home with my kids 3 days of the work week. Try scheduling more playdates and outings. I have noticed that the more time I spend trying to make my kids have the best childhood possible, I am happier, thus, less likely to relapse.
Also, try taking time out once a day- just for yourself and do something you want to do. Go for a walk by yourself in the evening, take some time out to read a good book, take a class in something you are interested in (I always wanted to take dance classes when I was younger, and now I take them through the Continuing Education in our local school district). Doing these things will hopefully, make you feel better about yourself, thus making you less depressed and less likely to relapse.
Feel free to PM as well if you just want to talk/vent.
