You must have some working thyroid left otherwise you would be extremely ill by now, you cannot survive without a thyroid and no replacement meds. When you register with a new GP ask for copies of your past blood results then post them on here for advice.
You REALLY need to know if you had a total or partial thyroidectomy! If you had a total and you are still alive then you should look into the possibility that your thyroid has grown back. I don't mean like it was to begin with but you might have cells growing back around whatever was left after your operation. A radioactive iodine scan will show up any active cells still left. Please let us know your progress solving this phenomenon, I find this fascinating and I think it has potential for regrowing important organs. (some organs do grow back, e.g. you can donate a piece of your liver and (it is said) your liver will grow back it's deficiency.)
However, your more immediate problem is that you have a hypothyroid condition which will need T4 or NDT. At least ask for a starter dose (50mcg Levo) and see how you feel. I would suggest you do not go back to the medics who operated on you and then did not prescribe medication - that was criminal neglect.
The diet my doctor was eat 1200 calories a day. I did it and lost 40 pounds so it does work. At first i was not sure but my doctor told me that diet works for people with thyroid issues. I have thyroid problems so if u stick to it the diet works. Good luck to you!!
