I'm not so sure, she sounds exactly like a girl who used to live across the street from me. She was about that age and lived with her divorced mother. The mother had a job that apparently was out of town so she didn't get home until around 5 or 6 in the afternoon. The daughter acted like she hated her. She would go after her for cigarettes as soon as she got home and when her mother had none for her because it would be illegal to buy them for her anyway she would call her mother a fucxing bixch, screaming it as loud as she could. When the mother wasn't there she would sit at the end of her driveway where boys would drive by to watch her show them what was under her skirt. They would pull into the driveway to "talk" to her where she would lean against the car with her sweater/blouse lifted so they could fondle/kiss her breasts in the window. They moved away after about a year and I don't know what ever became of them. I felt so bad for the mom who was working so hard to support them. The girl was in some type of state mandated program for unruly kids and the police would be over there about once a week.
But surely they can respond beautilly in love and they can probably also give as fine milk as any of the larger "colleagues" - all breasts expand two cup sizes when the milk is there. That has really nothing to with the amount of fat. And I'm sure they can also make you yourself go into extacy when they are strokes and admired in just the right way, by just the right person. You must remember that to us guys, a woman's breasts express so much and make you seem overflowing with something good that we need to be with ;o)
I think as you discover more of their power and wonderfulness, you'll be quite proud of having them be a part of your expression, and you will love having them - and no longer consider them "underdeveloped" or anything like that, just because someone else (or even even everybody else) has more fat on theirs.
I guarantee you, you can feel wonderful about having them, and someone who loves you will probably also feel it's something extra special and wonderful about you. My wife is somewhat like you, and that's at least how I always felt. Hers got a little heavier after nursing and as we got a little older (most women get a little heavier overall). I don't think almost-only-nipples-breasts seem like they express less, quite the contrary in fact. Sort of like when a riverbed is very wide, the water flows slowly and sedately, whereas when it narrows in, the same amount of water has to pass through, so it becomes a raging current ;o)
If in that semi-poetic example, you take the width of the riverbed to be the breast size, and the water to be what is expressed through the breasts from the love and femaleness inside, then I think you get the idea that while the actual amount may be the same, it can certainly seem like yours are much more intense and giving because the current is much stronger ;o)
Maybe that is a silly explanation, i don't know, but it's always difficult to explain feelings, so anyway, that was my five cents worth, and I really hope you get to feel wonderful about it as soon as asap ;o)
I don't have any reason to believe you are abnormal - unusual yes, but maybe you are the type who would love to be loved for specially you ... and not just "oh you are like everybody else, so why not you!" ;o) Then it is a good thing to be special. Best wishes! I think you will have the nicest secret smile ever when you get good about your special breasts ... and don't blame yourself for having worried about it, either. As a teen everyone is scared to be "different", and maybe everybody else were saying "oh, now we are becoming real women, now we fit an A cup = B = C ..." and so on. But let your revenge be that you take extra much in, when you realise that those magnificent body parts of yours indeed have everything in them, and they do express it all. I think it will mean a lot to you.
The feeling or notions you have had in the absense of that realisation, you can in a way take as proof that it exists - sort of like the nagging feeling of hunger proves that a sweet feeling of satisfaction also exists. I think it is like that with your breast feelings. You don't need to pep-talk yourself into believing what I say, but if it does make some sense at some point within you, just store it safely, and think about something else for a while. Then maybe at the right situation, it will pop up as almost something you always knew - and maybe you even did ;o)
I feel you it's like you are looking at my back with nipples
I also had no hips I looked like a 12year old and people would often mistake me for that when I was in my twenties I did not develop till I had an ovarian cyst in my early thirties and my periods became lighter after I stopped birth control pills in my earlier 20s I was unable to become pregnant
