Sweetly, first of all I have to tell you how incredibly BRAVE it is of you to post what you posted. And I want to give you a *BIG HUG*, because you've taken a big step - the most important step - in admitting that you have a problem.
I worked for a number of years in a Psych hospital and rehab, and I have been around recovery programs in various capacities also for a number of years.
First, only YOU can determine that you have an addiction. That being said...
You have described a very "classic" substance addiction. Being powerless to stop, it's not about getting high anymore, it's just taking the drug because you HAVE to, the self loathing, the promises you truly truly DO intend to keep but dont, and the other mental cartwheels that addicts put themselves through.
You are not alone!
It doesn't matter if your addiction is "physical" or "mental" at this point, you're addicted. You have subsituted one drug for another - food, cocaine, Phen, painkillers - you bounce from one to the other. It may not be an "immediate" bounce, like from one day to the next, but eventually the need is there to ingest something that will make "it" go away. And it does for a while, but it gets harder and harder, thus the increased quantities.
This is a key point, so I'm going to Bold it - when you have an addiction,
it's not WHAT you do/drink/eat, or
HOW MUCH you do/drink/eat, it's how it makes you FEEL or BEHAVE afterwards. If it's all out of control.
You can drink once a week, and still be an alcoholic.
You can do a drug once a week and your life be out of control.
Same principle with any other substance.
I am so sorry that you have been turned away by the medical persons that you have spoken to, but there ARE knowledgable people out there that will help you.
If you have medical insurance, it will be easier to get help - I hate to say it, but it's true. Try getting in touch with some treatment centers that deal with addiction - they
may be more receptive...unfortunately, then again, with the way our insurance industry is today, they may not. Just two days ago my girlfriend's husband was turned away from a place because he's not doing ENOUGH heroin at the moment for chrissakes. *shakes head*.
But then again, I had a friend Michael who DID go away to rehab due to an addiction to vicadin. He too was ordering online, and was up to like 30 of the damn things a day, and no one knew.
Either way, there is a bottom line here. If you really want the help, you will find it. If no treatment centers will help you, then you can go to Narcotics Anonymous, Alcoholics Anonymous, and/or Overeaters Anonymous meetings. Their doors are ALWAYS open, and they wont turn ANYONE away. And the love and acceptance you will find there will blow your mind! And you may also feel a sense of huge relief that the folks there TRULY understand, because they have all been where you are right now. And they GET it.
I had a friend years ago who was doing coke, (and not really a lot by typical "addict" standards), and one day just picked up the phone and called the NA hotline. That afternoon she met this other girl who took her to her first meeting. She never did go to rehab, she just dove into the Program and did what they told her to do. It's been about 20 years, and she's still sober!
I'm suggesting AA as well as NA or OA because in many areas, there are not a lot of NA/OA meetings, and the three programs are quite interchangeable anyway. A drug is a drug is a drug. And MOST of the people in AA have issues with drugs too. You may get one or two grizzled old timers who are "purists", but everyone ignores them anyway.
Going to a meeting does not mean you have to make instant changes, or let go of your drugs RIGHT THIS SECOND - I know that thought is immensely terrifying. All you need to attend is a WILLINGNESS to stop. Be open minded, and IDENTIFY and not COMPARE. Pray for help and strength and if you are really ready, your Higher Power WILL guide you.
Private therapy with a drug/alcohol counselor would be a good thing to look into also - someone who also specialized in food addictions too. Again, easier if you have insurance. But any counselor you go to that's worth their salt is going to tell you to go to meetings also anyway. One does not deal with addiction on a once-a-week outpatient basis alone. And "kicking the habit" on one's own alone doesn't work in the long run either.
This is a VERY serious disease, and it's a progressive disease. It may take a while to catch up with you, but every addiction that goes untreated results in jail, institution, or death. You are not a bad person, nor are you a weak person! You just have this issue. Whatever! Look, everyone has their demons, and some are just more visible and obvious than others. And some are more deadly. Every person on this board has issues, or we wouldn't be here. If your issue is drug addiction, you can either choose to take it by the horns, or let it ruin your life. It's really that simple.
My wonderful friend Michael, the one who was addicted to Vicadin? Well, he was active in the Program for just over 2 years, and sober, and then stopped going to meetings for various "reasons", and ended up dead alone in a hotel room last January. He was separated from his wife, and no one knows if it was an accidental overdose, or suicide. He went to the ER for stomach pains, and they prescribed him something that "gave him a heart attack". He either knew what it was they gave him and went to get it on purpose to get high again and it killed him, or maybe he didn't know and it happened accidently. I miss him dreadfully. And I'm going to kick his a s s when I catch up with him in heaven, cause if he was going to meetings and active in the program, he wouldn't have been alone that night. All he had to do was reach out.
So what I'm trying to tell you is you don't have to wait until you feel worse about your life, and you don't have to wait until you're doing "enough" sh*t to satisfy someone else's idea of what qualifies you for needing help. This insanity can stop. You CAN have a wonderful and fufilling life without the drugs.
But you really have to be READY. You may not be! You may not be in enough pain yet. You may not be uncomfortable enough yet to make changes. Let's face it - no one makes any change in any area of life until it becomes too uncomfortable NOT to make the change!

If you're not ready yet, that's okay too, the Program will be there for you when you are.
This part is the hardest part. The first steps are the toughest. I believe there is a part of you inside that knows exactly what you need to do, and is calling out to you, otherwise you wouldn't have posted! Listen to that little voice, it knows!
I have to put my little "disclaimer" here that everything I posted may not even apply to you. I cannot tell you that you have a problem, I cannot tell you if going to meetings and working the program is what you should do. I can't tell you that you are an addict. Only YOU can determine what you need to do! I don't want you to feel like I'm TELLING you! I just wanted to share and give you the benefit of my knowledge in this area in that it may help you to choose the best path for you.
I CAN tell you that, based upon what you shared, that I think meetings would be a huge help, and give you a great sense of peace. I think that you can find answers and new coping skills, and a renewed hope, not to mention a kick-a s s instant social life.
PLEASE keep us all posted, and let us know how things go for you! Feel free to PM me - I tentd to not check the PM's too regularly, but I do check them, and I would be happy to help.
You are a strong, resourceful, wonderful person with inner fortitude and a big heart. If no one told you that they love you today, I do, and God does too. *HUG*
