That's quite a medicine chest, so your doctor is happy enough to prescribe some meds!
Sadly, you are in a check and egg scenario. Many, many people have noted brain for, which clears once the bloods are wrangled into better shape.
I'd suggest in taking some small first steps, and your concentration and memory might be helped by making lists of your meal plans/food in the pantry. We don't shop every day (nightmare, nightmare!), but shop once a week, or longer, depending on where we are and what we have on. We buy, with meals in mind, so when we come home from our shop up we have x evening meals, and a similar number of breakfats and lunch options. We don't go as far as having a Monday = pork chops sort of routine, but I always know we have something at home we both like to eat. That makes things so much simpler.
Coincidentally, I was reading somewhere the other day that it has been found that those who have the same breakfast each day stick to diets for longer, as there are fewer decisions to be made, when under stress decision making can be quite tiring.
For now, you are not in control of your doctor's attitude and treatment of your Hashimoto's, but you are receiving medication for your diabetes. The absolute key to diabetes management is dietary control. That is a harsh and hard fact. Unless you are taking steps to moderate your diet, you are likely to head towards more and stronger drugs, and I reiterate, high blood sugars can negatively impact your mental state in themselves.
I'm sorry you're having a rotten time, and I'm sure I seem harsh in my approach, but there's little point in shilly-shallying around the facts. If you want to do something to help yourself, this forum will be a great resource and support for you. It's in your own hands.
