kbell, I am interested in this subject. I have to agree with what freedomlover wrote, especially the power of that complex t-square, which would have been `operating' for you from day 1.
I just have something to add in relation to the t-square itself, because I feel that it is within the intricacies of that t-square that the story lies for you. The original struggle (for want of a better word) is to be found in the opposition between your Neptune and Moon. That is a hugely sensitive aspect, and food sensitivities are just an extension of general physical & emotional sensitivity. That is, you sense things in your environment, and because you may not always have made sense of what you perceived (or you may not have allowed yourself to
believe what it is you sense) then your emotions in relation to what you perceive tend to be buried, or pushed into your body. This tends to be the first step in how sensitivity to environmental factors gets going in a body.
I would suggest that the way out, or the way of helping yourself to heal this is through understanding the Ceres-Jupiter conjunction in Pisces in the 3rd house. Given this conjunction is in Pisces, and close to the IC, and the IC is also ruled by Neptune, I feel you must look to the early home life for emotional triggers.
Also, you have Mars-Neptune conjunct (I also have that - not an enviable placement at all, so you need to understand how that manifests for you) and with Mars-Moon in opposition, conflict with the mother is indicated, and even if this conflict is suppressed, or even unconscious, it is still there.
The less it has been acted out openly, then the more damage it will do by holding it hidden within your very sensitive body. A sensitivity to any food at all is an unconscious block to nurturing oneself.
I would suspect that seeing that these levels of sensitivity are found in your family line that there are emotional patterns which are being repeated in each generation - and emotional patterns tend to be repeated within a family until someone consciously works on addressing them. Deep-seated fear of life is one such (quite common) emotional pattern.
