Hi Irina and Welcome,
First let me say your NOT alone. Sweetie, I feel the same way as you. I have lost in the past 150 lbs and regained 100 of them
I am the youngest of 7 kids so me and my sister next to my age were very negelcted. Both parents worked, and well they really had no time, so we found food as our only means of comfort, I do remember comments from my family as I got older about being fat and boy, don't they stick.
Its a vicious cycle, you eat cause your unhappy, your unhappy cause you eat...what the heck do you do? I wish I could tell you but I can't.
The only thing I can say is... keep trying, don't ever EVER give up, as long as there's an ounce of you that wants to be healthy, keep trying. I do believe that everyone has their "day" and ours will come if we so want it.
Keep posting, keep learning, keep wanting, keep talking, keep screaming for help, I think its the only way and there's nothing to be ashamed about. This site has oodles and oodles of people who are willing to take you under their wing, I think you will learn alot from them.
Hang in there and most important, Keep Praying
Hugs!!
