Just a vent but I gotta let it out...

I agree with a few things other have said:

therapy will help you a ton.

I had to tell my family (after my surgery) that I in essence have had an eating disorder all my life. I eat when I am stressed, angry, hurt. I over eat and then get sick. And them discussng my eating habits and my weight was a trigger for my eating disorder. So I needed them all to stop. Sure they meant well...but it was hurting me emotionally and physically. They stopped. It took some time, but they did.

Good luck and hugs.

Like Laura, no one ever comments on what I eat (and like Laura, I wouldn't tolerate it if they did).  Although I would encourage you to just tell your mother how hurtful her comments are, it may not be very realistic to expect that it will change anything.  (It might, of course, but she may be one of those people for whom it will go in one eat and out the other, and --just from the little bit of info in your post -- it sounds to me like she might be in the latter category.)  

Even if you are currently stuck living with her, that doesn't mean you have to subject yourself to her comments or listening to her discuss what you eat and your weight with someone else.  When she makes comments, let her know that it isn't ok, and if she continues, end the conversation and leave the room. If she is discussing you with your aunt, go to another room or outside so you don't have to hear it.  Even if you know she is having the discussion, that is less painful than having to actually hear it.  

I think you would benefit a lot from seeing a counselor... someone who can support you and be "in your corner" but also be objective and help you develop strategies for dealing with your mother, your financial and living situation, and that hurt child inside who wants to use food (by eating too much or not eating at all)  to soothe herself.

No, no one in my life polices what I eat anymore ( my dad did when I was a kid ), but I did have a moment last night with my husband that perplexed me a little. I measured out my protein and veggies...1/4 cup of each item. He looked at my plate, which only had 1/4 cup of fish on it at that point and said "That's all you're going to eat??" like he was utterly shocked by the amount. I said "Well, no...I'm going to get myself some zucchini too." He still looked a little confused, but said "Oh, okay."
It made me giggle a little bit because he's seen me measure out food before,but it took him a month to really notice how little my portions are.

Nope no one polices my food. My husband will state he "feels sorry for me" because I can't eat the amounts I used to. I told him not to It was a decision I made and I am elated with my results.

Some of my poorer food choices would make your mother's head spin but I also alot for the choices in my daily intake and only eat french fries or a poor food choice in limited amounts from time to time. I'm a big girl and the decisions are mine as I am the only one who will have to live with the results.

I know all about the hurt kid and those choices, please don't go there it isn't healthy for you.

I see a therapist and work out my issues behind a closed door with him and a bottle of water instead of behind a closed door with food as I did in the past. If you can afford to or have insurance coverage I'd highly recommend it.
