Food obsession or addiction?

Sometimes in the past, I wondered if I was addicted to food.  Out of no where I would get cravings so strong my mouth would salivate.  The mere thought of a type of food could bring me to my knees.  I am again wondering if I am addicted to food.  Chocolates, sweets, and coffee to be specific although I am quite sure I am addicted to the latter.

Over the past week, I started researching addition symptoms and cam across this handy dandy chart.

So I went down each row, to determine my dependency on certain foods and the amounts of foods I eat.  Here were my thoughts:
1.  It's already been proven that eating certain foods can simulate a "high" that is similar to that of opiate usage.  
2.  When I thought about how often I ate the evil foods, I came up with daily.  And yes, I realize certain foods are draining to my bank account.
3.  Looking at the third row, I laughed.  If you invite me to a "celebration" that is lacking food, I'm not going.  Point blank.  Period.
4/5.  There are some foods I won't eat in public because I don't want people to think negatively of me in the sense of, "I can't believe she is that fat and she's still eating that!"  Additionally, when I am home and getting a craving, I will sometimes resort to choices I'm not so proud of to get whatever I'm craving.  It has been somewhat normal for me to leave me children for a quick run to the store if the craving gets too intense.  I simply rationalize with myself that it's like me stepping out to check the mail.
6.  If I can't find what I'm craving I will substitute anything I can get my hands on.
7.  I do binge.  I stopped purging when I was in high school (which now that I think about it is probably what has led to my weight creeping up over the years).
8.  Since I am nearing my mid 30s and I'm still struggling with this issue, I think it's say to say I may need help to change.

I guess what I don't understand is if you CAN be addicted to food, why has no one stepped up to help those people who are struggling?  There are clinics for eating disorders like bulimia and anorexia.  But when someone is obese as I am, who do we turn to other than our general doctor?  People say that obesity is a major problem in America.  I think that major problem is the fact that the public thinks someone who suffers from obesity can help themselves or even has the money to help themselves.  

This is what prompted me to change.  According to this chart, which I know is not 100% accurate, I am extremely obese.  Unlike many others, I have my doctor and my brother's cousin's sister's nephew who moonlights as my therapist free of charge.  I guess all we can do for everyone else who is suffering and praying for help is pray that our country wakes up.  For some, this is just a feat to large to stand against alone.
