I also have Hypothyroidism since 1991. When you are diagnosed,you either have an under active thyroid(hypo) or an overactive one(hyper)...you can't have both. You will need to have frequent bloodtests to monitor the THS levels.
Most people have to take either Levothyroxine or Synthyroid for this,for the rest of your life. IT DOES NOT GO AWAY. Monitor it closely,or you could develope what they call "Graves disease" ,which is a form of cancer.
Soem doctors opt to remove a person's thyroid,if it is diseased.
Generally you do not go from being hypo to hyperthyroid, but if you are hypothyroid it can cause release of adrenaline which can mimic symptoms of hyperthyroidism (increased heart rate, anxiety, shaking, dizziness).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
