Hi and welcome!
You've had some fab advice in this thread, but I want to point something out:
If you change your diet before you have your second blood test, you will muck up your diagnosis.
I completely understand that you want to feel better, and that changing your diet may well be key to that. But if your test results are high and then low, you will create confusing and contradictory results.
So can I suggest that you spend the time until that 2nd test reading, planning and drooling over recipe books, but please don't change your diet until after the test.
