Dear Nicole, 
Sixteen months ago, I was where you are right now. I had battled my weight all of my life. I was always the fat kid, never chosen to be on teams and I've also had those horrible nights out with friends where they we're asked to dance and I was left sitting alone. I could never shop in regular stores and the clothes that did fit me had big huge ugly flowers and prints on them.  
Food was my best friend, food comforted me, food never let me down, food fixed all of my woes. Food understood me and never questioned me.  
I will say that there are people who are overweight and can stand to lose some weight, BUT.....there are people in this world who are addicted to food. And being one of them I speak form personal experience when I say that just changing lifestyle, agreeing to exercise and seeing a therapist doesn't work for the long haul.  
Nicole, you seriously need to re-evaluate your life. YOU and YOU alone need to decide if the food is worth your life. If it is, then fine.....continue eating like you do now and live your life until you die. Unfortunately it may well be that that time comes incrediably soon for you.  
If you truly are tired of this addiction, then find yourself a therapist to help you get to the bottom of when, why and how food became such an important part of your life....and then, you truly do need to consider having weight-loss surgery to further arm you with assistance in getting your addiction under control. For food addicts, a book, or a program or some "life" changes simply will NOT do it. Most food addicts need medical intervention.  
Currently there are two procedures out that could help you. Gastic Bypass OR Gastric Lap-Band. Neither are without risks but none the less they are the safest weight loss surgeries available to date.  
Sixteen months ago I underwent Gastric Lap-Band surgery. The surgery was the absolute easiest part of it. Since having my surgery, I have had therapy, and I'm learning daily to view food in a different way. I'm learning to redirect my attention when I'm hurt, stressed, sad, upset, lonely. Having the Lap-Band gives me that extra edge that I need by keeping me from overeating, binging, stuffing myself with food, while I learn to think differently about food.  
I've lost 83 pounds in sixteen months and I've gained muscle weight. I workout 5 to 7 days a week and I eat only when I'm hungry. I can go to the gym and do a powerful workout to match any fit person. I'm 40 years old. I'm almost able to pass the running part of a military fitness test for a person of my age. Sixteen months ago I couldn't walk a half flight of stairs without thinking I'de drop dead of heart failure before reaching the top. I still have 35 pounds to lose and for the first time in my life......I have NO DOUBT that I can and will do it. My lapband will help me not only to do it, but to maintain my weight loss once I reach goal. This surgery absolutely saved my life and gave me FREEDOM that I've craved for a very long time.  
I strongly urge you to take control of your life, investigate surgery, get a therapist and do this for yourself. It isn't easy.....despite what people think. Having weight loss surgery is NOT the easy way out. In fact it's the hardest thing I've ever done in my life. People who have never battled an addiction have NO IDEA what they are talking about. Food Addiction is a very real condition and addressing it soley with a "how to" book, a trainer, and a little therapy simply will NOT help the person addicted to food.  
Don't give up....take a stand for yourself, research the surgeries and do what you must do to save your life. Your family and friends I'm sure mean well.....however they are NOT in a position to help you with this. The only one who can is YOU, a surgeon and a therapist who specializes in eating disorders.  
Obese people who are ADDICTED to food are treated so terribly by most everyone in this country. And just as a book and a few changes in lifestyle will not help one who is battling anorexia or bulemia.....a book and a promise to stay on track will not help a person addicted to eating massive amounts of food. The fits, the crying, the getting angry when your not given food...is part of the addiction. And while "changing your lifestyle" is required, with a person addicted to food changing of lifestyle isn't enough. Medical, surgical intervention is NEEDED when dealing with a patient who needs to lose a massive amount of weight 
I wish you all the best....
