Welcome to eGullet, Melpy.
That is quite a list of allergens you have there. If this is new to you, it does sound as though you will be very challenged with carbs of just about any sort, including from garbanzo/chickpeas, being denied to you. You list scallops but no other shellfish - again if this is new for you, I suspect you may want to be cautious about using any other shellfish as well since allergies to similar things can 'grow'. My heart goes out to you - I would not be able to live well without pepper and garlic in particular. And I can see that salads may also be somewhat limited in your case as well without carrots, lettuce, tomatoes, beans, oranges, nuts. Luckily it seems that meats are mostly ok for you so I guess you are going on a high protein diet.
I have things I need to be cautious about eating for medical reasons but luckily having them (cooked) once in a while won't kill me (at least quickly) so I just avoid them most of the time. Most of those are vegetables and fruits. But even for me, the list gets longer and longer as I get older - and there is a possibility I may also now be developing a shellfish allergy (which would be a tragedy for me in terms of the loss of enjoyment of a whole category of foods that often make up most of the protein content I enjoy).
At any rate, I feel your pain though I can't really at this time offer you much in the way of any advice other than to just avoid those things to which you are sensitive and/or allergic. I am sure others may be of more help in that area however, especially if you can talk a bit more about specific types of foods or categories of things (salads, casseroles, stews, desserts, etc.) you DO like or need help with.
p.s. check everything you buy (processed foods) for soy ... and learn the variant names by which it may otherwise be identified. I have to avoid soy too - and I love Asian dishes. Through experimentation I have found that if I use black vinegar, sriracha, fish sauce, and toasted sesame oil (which I can see that in your case you need to avoid completely) and sometimes a bit of non-soy containing oyster sauce I can get a depth of flavour that is satisfying to replace soy sauce. Mushrooms are also good for injecting umami and good nutrition where soy is not an option.
