I had an overactive thyroid in my teens and had to have an operation to remove most of it. i had terrible symptoms, i dont know how i coped really. My whole life was on fast foreward, everyone thought i was mad, i was so nervous i would shake incontrollably, i couldnt control my bowels which was embarrassing at work, also my eyes bulged right out. i had to have beta blockers for my heart rate was 170 a minute, it was that bad. I had a check up at a private doctor and he told me i had recently had a heart attack which i knew nothing about, this was when i was very young. Its hard to believe that i managed to have 2 children and a relationship.
