First of all you have made the right choice by coming here. There are lots of like minded people who have a wealth of advice and experience to offer you.
I was 298lbs when I started my journey. I like you was addicted to food, and was terribly frightened of my weight killing me.It was what actually spurred me into action and made me DO THIS ONCE AND FOR ALL ! I researched and made a plan that I thought would suit me, my life style and taste. I took each ten pounds as a goal, and I just kept going. Even when it was tough I didn't give up. I wanted it to be the last time I would lose weight. It took me 14 months, and a lot of sweat and tears, but I am so glad I did it.
You will be too. Just put one foot in front of the other and try. When the going gets tough, come here and talk about your feelings. Weight loss is very much to do with conquering mental obstacles, and having the strength to achieve.
I wish you every success and know, with the right mindset that it can be done
