Mak78, please don't feel like your were oversharing. I find that as one of things that is most helpful here. If someone is uncomfortable with it, then they just move along. I really think a lot of issues with food comes from our backgrounds. I never had issues with food till I was in my mid 20's. All of a sudden I was eating a whole pizza and not even realizing it. This happened after the birth of my first child. I spent a lot of time by myself as my husband was traveling for work. I think I was just depressed and watching what I ate was the last thing on my mind.
I am not sure how you overcome a hard upbringing, I had one also and am still suffering from it. So I am sorry I don't have any answers for you. All I know is when I had children, I swore I would break the cycle. My kids would never end up like I did, thankfully I think I have. We can all change when we have to I guess.
