I'm not a doctor and I can't tell you what to do, so I'm not saying you should/shouldn't stop the thyroid med, but if it were me, I'd try to take steps to get all the other issues under control - blood sugar, blood pressure, cholesterol, weight
see if that helps.
exercise is very important and
no matter how much thyroid medication you take, if you have other things wrong, you aren't going to get well.
We still have that cortisol issue to work on...
