First, make sure you're increasing your fats. Protein is building blocks, not fuel. Fat and carbs are, so if you lower your carbs, increase your fat, not protein (provided your protein is adequate to maintain muscle - about 1g/lb of lean body mass). It will make the dietary changes far more manageable. 1g/lb of lean body mass for protein, the carb max that you have, fill the rest in with fat. Yes, it will seem like a ton. No, it's not going to kill you.

Second, stick with whole foods. Being nourished helps with the desire to binge and helps heal the physiological aspect of your relationship with food. It's amazing how many issues actually stem from being malnourished.

Third, find a reason to get outdoors whenever possible, and don't do sunscreen unless you're going to be on water or out for the entire day. Having a garden helps with this. Being in the sun helps you manufacture Vitamin D (and the fat in your diet will help, as well, and help absorb it), which will help keep your mood up, in turn keeping you from wanting to seek out comfort foods.

Also, find a good form of stress relief. Personally, I love boxing or other forms of martial arts or martial arts based, high intensity workout. That, or lifting heavy weights (which, by the way, seems to have a balancing effect on hormones, it's worth trying out even if it doesn't strike you as a way to relieve stress). Even just a good book might help.Both this and the outdoor thing is also good to keep you busy, so you get your mind away from what's stressing you, and away from food.

As for turning down food, simply say that you don't want it, or that you don't feel well when you eat it. If they have a problem with that, then that's their problem. (Note to those that would argue "just have a little bit" - those that have issues with food often can't "just have a little bit." It may work for some, but for others, it triggers addictive tendencies. It's better to say "no" outright, at least until the relationship with food has changed and disordered eating is under better control.)

Having food you made turned down by someone is not the end of the world. Everyone has likes and dislikes, and even if you like something, you may not be in the mood for it at the time. Someone who gets offended by that needs to grow up, in my opinion.

On a side note -- it might be worth considering your relationship with your family. They might be a primary trigger for you, and/or a toxic aspect in your life. For the sake of your health, it may be worthwhile to limit your interaction with them, particularly in situations where food is involved. If the only part of your relationship with your family that's a problem is food, then consider talking to them about your issues and concerns about your health, and refraining from food-related gatherings if you can't come to some kind of understanding on the matter. Family is important, certainly, but at some point, you have to put your own health and wellbeing above them (especially those who aren't dependent on you).

Thank you very much. For the advice.

As far as whole food... I know this probably sounds stupid, but what do you mean? Like organic? Or just not meals from a box? Or just whole grain?

Minimally processed, yes, and also as close to the items natural form as possible. For example, an apple is a whole food, apple juice is not (you're missing the fiber and nutrients in the skin and meat). Organic isn't necessarily required, especially if you're just starting out, though the higher quality the food you eat, the better.

I recommend avoiding grains in general (whole or otherwise) for a number of different reasons, not the least of which being the strong link I've seen in my research between PCOS and gluten intolerance, the similarities in grain proteins to cross-react with gluten, and simply the high amount of starch/carbs for relatively low nutrient content. Instead, trade those grains for vegetables, which are far more nutrient dense.

As far as my family goes... They are the only people I interact with at the moment... I can't avoid them because I live with my brother (who really doesn't get the fact if I don't cut back on the carbs/sugar I get to hang out in the restroom for a while) and I work for my aunt. Our relationship is ok. She is diabetic but uncontrolled, and gets what I'm going through a little too much without being super helpful, so when it comes to food... She literally said "if you figure it out let me know" when I asked her about this. My parents are great if sometimes forgetful now that I'm out of the house, so they are generally fairly sensitive to my needs when I go there. But literally 10/12 adults in my life are significantly overweight. And to be frank I don't know how to make friends without having school for a catalyst (even then it's hard but at least doable).

I can sympathize with trying to deal with PCOS and guys. My husband didn't really understand why I wasn't losing weight. Since he could basically just think about eating better and lose weight (not even tracking, not even really working out), the idea that I was not only putting in significant effort, but ten times more effort than he was, and still not seeing results, was completely foreign to him. He thought I simply wasn't trying hard enough. Suffice to say, he got that lesson drilled into him pretty hard and fast (thankfully, he was genuinely trying to help, and so, was receptive to what I was telling him).

Finding a hobby that gets you out of the house and interacting with others will help you make friends that are more in line with your goals. Check out meetup.com for various activity groups in your area. They're often free, and can help you meet people that would be more supportive of your attempts to get healthy.

If your aunt is genuinely willing (I'm hoping she's willing and just uninformed; being unwilling in her condition is going to kill her, even if she's acting willing -- acting willing and actually doing something are two different things), you two might want to try something like the Primal Blueprint 30-day challenge - http://www.marksdailyapple.com/the-primal-blueprint-30-day-challenge/ (I recommend it, because the Primal Blueprint specifically focuses on helping metabolic disorders). Even if she's not, I recommend picking up The Primal Blueprint (and/or checking out the website) and giving it a try. It will help you work with your Metformin, instead of against it (it recommends a lower-carb, higer-fat diet, which is what generally works best for PCOS, especially for those of us on Metformin), and it will provide rather in-depth information on how to have a whole-foods-based diet and why the Standard American Diet has made us insulin resistant and unhealthy. Perhaps if you change your diet and find success, you'll be able to influence your family.
