new to this 220 lbs to lose!

I am a 23 year old hair stylist who justs wants to be normal. I have always been chubby and I never could be classified as thin even when I was little..... I remember in highschool thinking I was huge as a 12 and would give anything to be that again. Stress and whatever else made my eating spiral out of control and I quickly made food the love of my life. I love food and it has made me the happiest and saddest person i have ever been. But I'm tired of it being an addiction that is my worst enemy. I am currently 370 lb. and I can't live like this anymore. From my job to my love for fashion myself as well as my friends always made me feel smaller than I was. I have never been the girl that didnt care about her appearance I work pretty dang hard to be a stylish fat girl and Im ready to be able to shop at a normal store and sit in a normal chair and not worrry about the things little people dont have to deal with. I want to be 150 lbs....and as far away as that feels I am willing to take on challenge but I need your help to keep me on track.
